Using the high-resolution K = 600 magnetic spectrometer, 98 states in S35 were identified up to 16-MeV excitation energy, including 47 previously unobserved states. Angular distributions and spectroscopic factors, including isobaric analog-state contributions, were extracted for 81 levels. A pronounced j dependence in the angular distributions of ℓ=2 states provides refined insights into the spin-orbit splitting. Finite-range adiabatic distorted-wave approximation calculations qualitatively reproduce the observed j dependence. Comparisons of the measured 1d5/2 spectroscopic strength distribution with large-scale shell-model and ab initio calculations show good agreement overall, and the robustness of the N=20 shell closure in S36 is confirmed... https://escholarship.org/uc/item/45t2z352 Mon, 29 Jun 2026 00:00:00 +0000 Jongile, S Wiedeking, M https://orcid.org/0000-0003-4983-3882 Sorlin, O Neveling, R Hebborn, C Keeley, N Nowacki, F Soma, V Lemasson, A Papka, P Adsley, P Avaa, AA Azaiez, F Donaldson, LM Flavigny, F Jivan, H Jones, P Kenfack, D Kheswa, NY Khumalo, TC Makhathini, L Malatji, KL https://orcid.org/0000-0001-7810-3366 Mthembu, SH Nemulodi, F Netshiya, AA Pellegri, L Smit, FD https://escholarship.org/uc/item/9mc8x1bm Parton distribution functions (PDFs) are central to precision QCD phenomenology. Their Mellin moments can be computed on the lattice, but direct determinations using local operators, besides ⟨x⟩, face severe challenges from reduced hypercubic symmetry, limiting results to the lowest moments. A recently proposed method resolves these issues using gradient flow. We demonstrate the efficacy of this method by computing ratios of flavor nonsinglet pion PDF moments up to ⟨x^{5}⟩ on four lattice spacings at m_{π}≃411  MeV. The moments and reconstructed PDF agree quantitatively with recent phenomenological extractions. https://escholarship.org/uc/item/9mc8x1bm Thu, 25 Jun 2026 00:00:00 +0000 Francis, Anthony Fritzsch, Patrick Harlander, Robert V Karur, Rohith Kim, Jangho Kohnen, Jonas T Pederiva, Giovanni Pefkou, Dimitra A Rago, Antonio Shindler, Andrea Walker-Loud, André https://orcid.org/0000-0002-4686-3667 Zafeiropoulos, Savvas https://escholarship.org/uc/item/9dd2h139 The measurement of three-dimensional femtoscopic correlations between identical charged kaons (K±K±) produced in p–Pb collisions at center-of-mass energy per nucleon pair $$\sqrt{{s}_{\text{NN}}}=5.02$$ TeV with ALICE at the LHC is presented for the first time. This measurement, supplementary to those in pp and Pb–Pb collisions, allows understanding the particle-production mechanisms at different charged-particle multiplicities and provides information on the dynamics of the source of particles created in p–Pb collisions, for which a general consensus does not yet exist. It is shown that the measured source sizes increase with charged-particle multiplicity and decrease with increasing pair transverse momentum. These trends for K±K± are similar to the ones observed earlier in identical charged-pion and $${\text{K}}_{\text{s}}^{0}{\text{K}}_{\text{s}}^{0}$$ correlations in Pb–Pb collisions at various energies and in π±π± correlations in p–Pb collisions at $$\sqrt{{s}_{\text{NN}}}=5.02$$... https://escholarship.org/uc/item/9dd2h139 Thu, 25 Jun 2026 00:00:00 +0000 Acharya, S Agarwal, A Aglieri Rinella, G Aglietta, L Agnello, M Agrawal, N Ahammed, Z Ahmad, S Ahn, SU Ahuja, I Akindinov, A Akishina, V Al-Turany, M Aleksandrov, D Alessandro, B Alfanda, HM Alfaro Molina, R Ali, B Alici, A Alizadehvandchali, N Alkin, A Alme, J Alocco, G Alt, T Altamura, AR Altsybeev, I Alvarado, JR Andrei, C Andreou, N Andronic, A Andronov, E Anguelov, V Antinori, F Antonioli, P Apadula, N Aphecetche, L Appelshäuser, H Arata, C Arcelli, S Arnaldi, R Arneiro, JGMCA Arsene, IC Arslandok, M Augustinus, A Averbeck, R Averyanov, D Azmi, MD Baba, H Badalà, A Bae, J Baek, YW Bai, X Bailhache, R Bailung, Y Bala, R Balbino, A Baldisseri, A Balis, B Banoo, Z Barbasova, V Barile, F Barioglio, L Barlou, M Barman, B Barnaföldi, GG Barnby, LS Barreau, E Barret, V Barreto, L Bartels, C Barth, K Bartsch, E Bastid, N Basu, S Batigne, G Battistini, D Batyunya, B Bauri, D Bazo Alba, JL Bearden, IG Beattie, C Becht, P Behera, D Belikov, I Bell Hechavarria, ADC Bellini, F Bellwied, R Belokurova, S Beltran, LGE Beltran, YAV Bencedi, G Bensaoula, A Beole, S Berdnikov, Y Berdnikova, A Bergmann, L Besoiu, MG Betev, L Bhaduri, PP Bhasin, A https://escholarship.org/uc/item/9db1f55b We present a nonperturbative determination of the pion valence parton distribution function (PDF) moment ratios up to , using the gradient flow in lattice quantum chromodynamics (QCD). As a testing ground, we employ SU(3) isosymmetric gauge configurations generated by the OpenLat initiative with a pseudoscalar mass of . Our analysis uses four lattice spacings and a nonperturbatively improved action, enabling full control over the continuum extrapolation, and the limit of vanishing flow time, . The flowed ratios exhibit O( ) scaling across the ensembles, and the continuum-extrapolated results, matched to the scheme at using next-to-next-to-leading order matching coefficients, show only mild residual flow-time dependence. The resulting ratios, computed with a relatively small number of configurations, are consistent with phenomenological expectations for the pion’s valence distribution, with statistical uncertainties that are competitive with modern global fits. These findings... https://escholarship.org/uc/item/9db1f55b Thu, 25 Jun 2026 00:00:00 +0000 Francis, Anthony Fritzsch, Patrick Karur, Rohith Kim, Jangho Pederiva, Giovanni Pefkou, Dimitra A Rago, Antonio Shindler, Andrea Walker-Loud, André https://orcid.org/0000-0002-4686-3667 Zafeiropoulos, Savvas https://escholarship.org/uc/item/8k19p851 We study energy-energy correlators (EECs) in annihilation and deep inelastic lepton-hadron scattering (DIS), focusing on aspects of nonperturbative physics in these observables. We introduce the EEC jet functions and investigate the infrared behavior of both small-angle EECs and angle-integrated EECs by performing explicit one-loop calculations. The factorization and universality of the EECs in these processes are demonstrated. A matching scheme is proposed to smoothly connect kinematic regions where different scaling behaviors with jet energy are observed. In combination with the next-to-leading order correction, this matching provides a good description of the EEC data and simulations in high-energy annihilation. Predictions for DIS processes for future electron-ion collider kinematics are also presented. https://escholarship.org/uc/item/8k19p851 Thu, 25 Jun 2026 00:00:00 +0000 Guo, Yuxun Vogelsang, Werner Yuan, Feng https://orcid.org/0000-0001-9979-3853 Zhao, Wenbin https://orcid.org/0000-0001-8324-6134 https://escholarship.org/uc/item/6v7346g2 Networks of radiation detectors provide a platform for real-time radioactive source detection and identification in urban environments. Detection algorithms in these systems must adapt to naturally-occurring changes in background, which requires well-characterized relationships between precipitation events and their corresponding radiological signature. We present a quantitative and qualitative description of rain-induced radon progeny deposition events occurring in Chicago from September 2023 to February 2024. We measure ambient gamma radiation levels, precipitation rate, temperature, pressure, and relative humidity in a network of sensor nodes. For each identified precipitation period, we decompose spectra into static- and radon-associated components as defined by a non-negative matrix factorization (NMF) algorithm. We find a consistent power-law relationship between a precipitation-dependent peak of the radon progeny proxy (RPP) and the peak strength of the radon-associated... https://escholarship.org/uc/item/6v7346g2 Thu, 25 Jun 2026 00:00:00 +0000 Das, S Abgrall, N https://orcid.org/0009-0005-0777-8661 Bandstra, MS https://orcid.org/0000-0002-6403-7895 Cooper, RJ https://orcid.org/0000-0002-5669-2961 Kim, Y Rofors, E https://orcid.org/0000-0002-9674-7947 Sankaran, R Shahkarami, S https://escholarship.org/uc/item/0rz293xt We report improved measurements of the all flavor astrophysical neutrino spectrum with IceCube by combining complementary neutrino samples in two independent analyses. Both analyses show evidence of a harder spectrum at energies below ∼30  TeV compared to higher energies where the spectrum is well characterized by a power law. The spectrum is better described by a log parabola or a broken power law, the latter being the preferred model. Both, however, reject a single power law over an energy range 5 TeV-10 PeV with a significance >4σ, providing new constraints on properties of cosmic neutrino sources. https://escholarship.org/uc/item/0rz293xt Thu, 25 Jun 2026 00:00:00 +0000 Abbasi, R Ackermann, M Adams, J Agarwalla, SK Aguilar, JA Ahlers, M Alameddine, JM Ali, S Amin, NM Andeen, K Arguelles, C Ashida, Y Athanasiadou, S Axani, SN Babu, R Bai, X Baines-Holmes, J V., A Balagopal Barwick, SW https://orcid.org/0000-0003-2050-6714 Bash, S Basu, V Bay, R Beatty, JJ Tjus, J Becker Behrens, P Beise, J Bellenghi, C Benkel, B BenZvi, S Berley, D Bernardini, E Besson, DZ Blaufuss, E Bloom, L Blot, S Bodo, I Bontempo, F Motzkin, JY Book Meneguolo, C Boscolo Boser, S Botner, O Bottcher, J Braun, J Brinson, B Brisson-Tsavoussis, Z Burley, RT Butterfield, D Campana, MA Carloni, K Carpio, J Chattopadhyay, S Chau, N Chen, Z Chirkin, D Choi, S Clark, BA Coleman, A Coleman, P Collin, GH Borja, DA Coloma Connolly, A Conrad, JM Corley, R Cowen, DF De Clercq, C DeLaunay, JJ Delgado, D Delmeulle, T Deng, S Desiati, P de Vries, KD de Wasseige, G DeYoung, T Diaz-Velez, JC DiKerby, S Dittmer, M Domi, A Draper, L Dueser, L Durnford, D Dutta, K DuVernois, MA Ehrhardt, T Eidenschink, L Eimer, A Eller, P Ellinger, E Elsasser, D Engel, R Erpenbeck, H Esmail, W Eulig, S Evans, J Evenson, PA Fan, KL Fang, K Farrag, K Fazely, AR Fedynitch, A Feigl, N https://escholarship.org/uc/item/7j80b1zm For LHC Run 3, the ALICE Time Projection Chamber was upgraded to operate in continuous readout mode. Interaction rates of up to 50 kHz in Pb-Pb collisions require real-time processing of more than 3 TB s-1 of raw detector data. This requirement is met by a custom FPGA-based processing pipeline that performs the complete front-end data treatment fully in-stream, including common-mode correction, pedestal subtraction, ion-tail filtering, zero suppression, and dense data packing. A central element of the design is a highly parallel common-mode correction algorithm operating directly on the streaming data. It robustly identifies signal-free readout channels on a time-bin basis and applies pad-dependent scaling to compensate for local variations in capacitive coupling in the GEM readout. In combination with pedestal subtraction and ion-tail filtering, this enables accurate baseline restoration under extreme high-occupancy conditions, preventing signal loss while efficiently suppressing... https://escholarship.org/uc/item/7j80b1zm Wed, 24 Jun 2026 00:00:00 +0000 Alme, J Alt, T Andrei, C Anguelov, V Appelshäuser, H Arslandok, M Averbeck, R Ball, M Barnaföldi, GG Becht, P Bellwied, R Berdnikova, A Blidaru, B Boldizsár, L Bratrud, L Braun-Munzinger, P Bregant, M Britton, CL Büsching, H Caines, H Chatzidaki, P Christiansen, P Cormier, TM Döpper, L Ehlers, R https://orcid.org/0000-0002-3897-0876 Fabbietti, L Flor, F Gaardhøje, JJ Munhoz, MG Garabatos, C Gasik, P Gera, Á Glässel, P Grünwald, N Gündem, T Gunji, T Hamagaki, H Harris, JW Hauer, P Hellbär, E Helstrup, H Herghelegiu, A Herrera, HD Hernandez Hou, Y Hughes, C Ivanov, M Jäger, J Ji, Y Jung, J Jung, M Ketzer, B Kirsch, S Kleiner, M Knospe, AG Korwieser, M Kowalski, M Lautner, L Lesch, M Lippmann, C Mantzaridis, G Majka, RD Marin, A Markert, C Masciocchi, S Matyja, A Meres, M Mihaylov, DL Miśkowiec, D Munzer, RH Murakami, H Münning, K Nassirpour, A Nattrass, C Nielsen, BS Noije, WAV Da Silva, AC Oliveira Oskarsson, A Oyama, K Österman, L Pachmayer, Y Paić, G Petris, M Petrovici, M Planinic, M Rasson, J Read, KF Rehman, A Renfordt, R Riedel, A Røed, K Röhrich, D Rubio, E Rusu, A Sadhu, S Sanches, BCS Schambach, J Schmah, A Schmidt, C Schmier, A Schweda, K https://escholarship.org/uc/item/7gh6f6vg The IceCube Upgrade is an extension of the existing IceCube Neutrino Observatory and will be deployed in the 2025–2026 austral summer. It will significantly improve the sensitivity of the detector to atmospheric neutrino oscillations. The existing 86-string IceCube array contains a dense in-fill known as DeepCore which is optimized to measure neutrinos with energies down to a few GeV. The IceCube Upgrade will consist of seven new densely instrumented strings placed within the DeepCore volume to further enhance the performance in the GeV energy range. The additional strings will feature new optical modules, each containing multiple photomultiplier tubes (PMTs), in contrast to the existing modules that each contain a single PMT. This will more than triple the number of PMT channels with respect to the current IceCube configuration, allowing for improved detection efficiency and reconstruction performance at GeV energies.

For a number of typical fission cases, samples of 104 shape evolutions are generated by Langevin simulation and, subsequently, for each such evolution, the nucleon exchange transport theory previously developed for damped nuclear reactions is used to obtain the development of the fragment spin-spin distribution within the Fokker-Planck transport framework. The characteristic evolution of both parallel and perpendicular spin components is discussed. A common feature is that the rotational modes fall out of equilibrium before scission when the temperature rises rapidly while the concurrent shrinking of the neck suppresses further exchange. A number of fission observables are extracted from the event ensembles: the distribution of the magnitude of the fragment spin and its orientation relative to the fission axis, as well as the correlation between the two spins and the distribution... https://escholarship.org/uc/item/3wg2c91q Wed, 24 Jun 2026 00:00:00 +0000 Randrup, Jørgen Nadtochy, Pavel Schmitt, Christelle Mazurek, Katarzyna https://escholarship.org/uc/item/36h516fc The IceCube South Pole Neutrino Observatory has discovered the presence of a diffuse astrophysical neutrino flux at energies of TeV and beyond using neutrino induced muon tracks and cascade events from neutrino interactions. We present two analyses sensitive to neutrino events in the energy range 1 TeV to 10 PeV, using more than 10 years of IceCube data. Both analyses consistently reject a neutrino spectrum following a single power-law with a significance of >4σ in favor of a broken power law. We describe the methods implemented in the two analyses, the spectral constraints obtained, and the validation of the robustness of the results. Additionally, we report the detection of a muon neutrino in the medium energy starting events sample, or MESE, with an energy of 11.4-2.53+2.46 PeV, the highest energy neutrino observed by IceCube to date. The results presented here show insights into the spectral shape of astrophysical neutrinos, which has important implications for inferring... https://escholarship.org/uc/item/36h516fc Wed, 24 Jun 2026 00:00:00 +0000 Abbasi, R Ackermann, M Adams, J Agarwalla, SK Aguilar, JA Ahlers, M Alameddine, JM Ali, S Amin, NM Andeen, K Arguelles, C Ashida, Y Athanasiadou, S Axani, SN Babu, R Bai, X Baines-Holmes, J V., A Balagopal Barwick, SW https://orcid.org/0000-0003-2050-6714 Bash, S Basu, V Bay, R Beatty, JJ Tjus, J Becker Behrens, P Beise, J Bellenghi, C Benkel, B BenZvi, S Berley, D Bernardini, E Besson, DZ Blaufuss, E Bloom, L Blot, S Bodo, I Bontempo, F Motzkin, JY Book Meneguolo, C Boscolo Boser, S Botner, O Bottcher, J Braun, J Brinson, B Brisson-Tsavoussis, Z Burley, RT Butterfield, D Campana, MA Carloni, K Carpio, J Chattopadhyay, S Chau, N Chen, Z Chirkin, D Choi, S Clark, BA Coleman, A Coleman, P Collin, GH Borja, DA Coloma Connolly, A Conrad, JM Corley, R Cowen, DF De Clercq, C DeLaunay, JJ Delgado, D Delmeulle, T Deng, S Desiati, P de Vries, KD de Wasseige, G DeYoung, T Diaz-Velez, JC DiKerby, S Dittmer, M Domi, A Draper, L Dueser, L Durnford, D Dutta, K DuVernois, MA Ehrhardt, T Eidenschink, L Eimer, A Eller, P Ellinger, E Elsasser, D Engel, R Erpenbeck, H Esmail, W Eulig, S Evans, J Evenson, PA Fan, KL Fang, K Farrag, K Fazely, AR Fedynitch, A Feigl, N https://escholarship.org/uc/item/8qj8b267 We study finite-volume (FV) corrections to determinations of via lattice quantum chromodynamics (QCD) using analytic results and numerical analysis. We observe that heavy Baryon chiral perturbation theory does not provide an unambiguous prediction for the sign of the FV correction, which is not surprising when one also considers large- constraints on the axial couplings. We further show that nonmonotonic FV corrections are naturally allowed when one considers either including explicit -resonance degrees of freedom or one works to higher orders in the chiral expansion. We investigate the potential impact of these FV corrections with a precision study of using models of FV corrections that are monotonic and nonmonotonic. Using lattice QCD data that is approximately at the 1% level of precision, we do not see significant evidence of nonmonotonic corrections. Looking forward to the next phase of lattice QCD calculations, we estimate that calculations that are between the 0.1%... https://escholarship.org/uc/item/8qj8b267 Wed, 17 Jun 2026 00:00:00 +0000 Hall, Zack Pefkou, Dimitra A Meyer, Aaron S https://orcid.org/0000-0001-7937-8505 Richardson, Thomas R Briceño, Raúl A Clark, MA Hoferichter, Martin Mereghetti, Emanuele Monge-Camacho, Henry Morningstar, Colin Nicholson, Amy Vranas, Pavlos Walker-Loud, André https://escholarship.org/uc/item/5cc77414 Using the Colour Glass Condensate description of electron-nucleus collisions at high energy, we study the diffractive production of a pair of jets with transverse momenta much larger than the nuclear saturation momentum Qs. At leading order in the QCD coupling, the di-jet cross-section exhibits transverse-momentum dependent (TMD) factorisation, with a gluon diffractive TMD distribution (DTMD) which is controlled by gluon saturation and describes the transverse-momentum imbalance between the produced jets. The next-to-leading corrections generate the various quantum evolutions of the diffractive gluon distribution. We focus on the Collins-Soper-Sterman (CSS) evolution which describes the change in the gluon DTMD when increasing the “hard scale” (the typical transverse momentum of the di-jets). We consider two different representations for this equation, one in transverse-momentum space, the other one in transverse-coordinate space. They are not fully equivalent with each other... https://escholarship.org/uc/item/5cc77414 Wed, 17 Jun 2026 00:00:00 +0000 Iancu, E Triantafyllopoulos, DN Wei, SY Yuan, F https://orcid.org/0000-0001-9979-3853 https://escholarship.org/uc/item/0j2072bf The STAR experiment at RHIC at Brookhaven National Laboratory completed the installation of an endcap time-of-flight subsystem in February 2019. The subsystem provided essential mid-rapidity particle identification for the fixed-target portion of phase II of the STAR beam energy scan. The fixed-target program allowed the experiment to access center-of-mass energies from s N N = 3 . 0 GeV to s N N = 7 . 7 GeV, not accessible by colliding beams. The system’s detectors and readout electronics were designed for the CBM experiment at FAIR and adapted for use at STAR. In this paper, we describe the details of the system in terms of geometrical layout, acceptance, calibration, hit reconstruction, and particle identification. The system achieved a time resolution of about 70 ps and a track-matching efficiency of about 70%, meeting the design goals of the project. https://escholarship.org/uc/item/0j2072bf Wed, 17 Jun 2026 00:00:00 +0000 Labonté, Mathias C Cebra, Daniel Sweger, Zachary https://orcid.org/0000-0003-4485-4182 Eppley, Geary Geurts, Frank Söhngen, Yannick Herrmann, Norbert Rubio, Esteban Weidenkaff, Philipp Deppner, Ingo Loizeau, Pierre-Alain Frühauf, Jochen Emschermann, David Seck, Florian Tlusty, David Hu, Dongdong Sun, Yongjie Ljubicic, Tonko Wang, Yi https://escholarship.org/uc/item/9pn486hr In this study, we examine the effect of the so-called Centrality Bin Width Correction (CBWC) on the measurement of (net-)proton number cumulants in nucleus-nucleus collisions. We present an analytically tractable model, which includes correlations between multiplicity and proton number similar to those generated by the decay of baryon resonances. Within this model, we analyze the circumstances under which the CBWC method correctly removes the undesired effects of volume or impact parameter fluctuations. Additionally, we explore situations where the method fails and produces misleading results. https://escholarship.org/uc/item/9pn486hr Thu, 11 Jun 2026 00:00:00 +0000 Friman, Bengt Koch, Volker https://orcid.org/0000-0002-2157-2791 https://escholarship.org/uc/item/58z6z10q Next-generation neutrinoless double-beta ( $\mathbf {0}\boldsymbol { u }\boldsymbol {\beta }\boldsymbol {\beta }$ ) decay searches require a large detector/isotope mass and very low radioactive backgrounds.

Policy-makers have long sought to translate concepts used in the nuclear and conventional domains to state competition in the cyber domain—not least whether the concept of deterrence that underpins the nuclear realm travels. Unfortunately, analysts face two difficult challenges associated with analyzing cyber deterrence. First, using the historical record for empirical data, scholars are only able to observe deterrence failure—with no guarantee that the observed instances of deterrence failure represent a complete set. Second, the “cyber” domain is interminably difficult to both analyze and model—with similar selection effects associated with which types of cyber attacks are detected. As evidenced by our study leveraging a new experimental wargame, TANTALUS, wargaming methods can solve some of these challenges.

Each LD was assembled with a large cubic light-emitting crystal (45 mm side) using the recently developed CROSS mechanical structure. The detector array was operated at milli-Kelvin temperatures in a pulse-tube cryostat at the Canfranc underground laboratory in Spain. We achieved good performance with scintillating bolometers from CROSS, made of Li2 100MoO4 crystals and used as reference detectors of the setup, and with all LDs tested (except for a single device that encountered an electronics issue). No leakage current was observed for 8 LDs with an electrode bias up to 100 V.

Using 13.1 yr of IceCube data, we present a follow-up search for neutrino sources in the northern sky. NGC 1068 remains the most significant neutrino source among 110 preselected gamma-ray emitters while also being spatially compatible with the most significant location in the northern sky. Its energy spectrum is characterized by an unbroken power-law with spectral index γ = 3.4 ± 0.2. Consistent with previous results, the observed neutrino flux exceeds its gamma-ray counterpart by at least 2 orders of magnitude. Motivated by this disparity and the high X-ray luminosity of the source, we selected 47 X-ray-bright Seyfert galaxies from the Swift/BAT spectroscopic survey that were not included in the list of gamma-ray emitters. When testing this collection for neutrino emission, we observe a 3.3σ excess from an ensemble of 11 sources, with NGC 1068 excluded from the sample.

The QGP forms in ultrarelativistic heavy-ion collisions. Anisotropic flow coefficients, quantifying the azimuthal expansion of produced matter, probe QGP properties. Flow measurements in high-energy heavy-ion collisions show a distinctive grouping of anisotropic flow for baryons and mesons at intermediate transverse momentum – a feature associated with flow imparted at the quark level, confirming QGP existence. The observation of QGP-like features in proton–proton and proton–ion collisions has sparked debate about QGP formation in smaller systems.

Only a small fraction of the observed astrophysical neutrinos can be explained by known sources. Neutrino production is thought to occur in energetic environments that are ultimately powered by the gravitational collapse of dense regions of the large-scale mass distribution in the universe. Whatever their identity, neutrino sources likely trace this large-scale mass distribution. The clustering of neutrinos with a tracer of the large-scale structure may provide insight into the distribution of neutrino sources with respect to redshift and the identity of neutrino sources.

This concept is then applied to authenticating the radiation measurement equipment in nuclear weapon verification systems and conducting demonstration fuzz testing measurements with a sodium iodide (NaI) gamma ray spectrometer. We show that physical differential fuzz testing can detect two types of tamper attempts, and conclude that it is a promising framework for authenticating future cyber-physical systems in nuclear arms control, safeguards, and beyond. https://escholarship.org/uc/item/96m9b586 Thu, 21 May 2026 00:00:00 +0000 Vavrek, Jayson R https://orcid.org/0000-0002-6809-9380 Zhou, Luozhong Boverhof, Joshua https://orcid.org/0000-0003-2553-6613 Heymann, Elisa R Miller, Barton P Peisert, Sean https://orcid.org/0000-0003-3566-9719 https://escholarship.org/uc/item/45d3n8mr An understanding of the pulse shape of organic scintillators can provide insight into scintillation mechanisms and inform the selection of the optimal detector material for a given application. Although the timing properties of organic scintillators have been extensively studied, significant discrepancies persist in reported rise and decay times. New plastic scintillating media have also been developed in recent years for which no literature data exist. The goal of this work is to provide high-precision measurements of the pulse shape of a suite of fast plastic organic scintillators from Eljen Technology—EJ-200, EJ-204, EJ-208, EJ-230, EJ-232, and EJ-232Q (with 0.5% benzophenone)—under excitation from γ -ray sources.

We extend our prior studies to third- and fourth-order cumulants in both coordinate- and momentum-space acceptances and integrated correlation functions (factorial cumulants). We find that, even near the critical point, non-Gaussian cumulants equilibrate on timescales comparable to those of the second-order cumulants, but show stronger finite-size effects. The presence of interactions and of the critical point leads to strong deviations of the cumulants from the ideal-gas baseline in coordinate space; these deviations are expected to persist in momentum space in the presence of collective expansion.

This value is one-sixth of that of real photoproduction at backward angles.

In this paper, a new method is explored for studying vector-meson global spin alignment in heavy-ion collisions by examining the two-dimensional (2D) polar and azimuthal angle distribution. This method allows simultaneous extraction of ρ00 and off-diagonal spin density matrix elements (SDMEs), providing unique access to local quark-antiquark spin correlations and spin hydrodynamics in quark-gluon plasma. The new 2D method also removes potential biases from nonzero off-diagonal SDMEs on ρ00 with the 1D method.

The framework uses non-negative matrix factorization (NMF) and clustering to learn groups of similarly-performing channels and sweep through various learned channel combinations to optimize the performance tradeoff of including worse-performing channels for better total efficiency. In this work, we integrate the pyGEM uranium enrichment assay code with our spectre-ml framework, and show that the U-235 enrichment relative uncertainty can be directly used as an optimization target. We find that this optimization reduces relative uncertainties after a 30 -minute measurement by an average of 20%, as tested on six different H3D M400 CdZnTe spectrometers, which can significantly improve uranium non-destructive assay measurement times in nuclear safeguards contexts. Additionally, this work demonstrates that... https://escholarship.org/uc/item/4z60j9zh Tue, 5 May 2026 00:00:00 +0000 Vavrek, Jayson R https://orcid.org/0000-0002-6809-9380 MacDonald, Thomas D Parrilla, Hannah S Deshmukh, Nikhil S Zalavadia, Mital A McDonald, Benjamin S https://escholarship.org/uc/item/4xx7x4f8 The 247-keV state in ^{54}Sc, populated in the β decay of ^{54}Ca, is reported here as a nanosecond isomer with a half-life of 26.0(22) ns. The state is interpreted as the 1^{+} member of the πf_{7/2}⊗νf_{5/2} spin-coupled multiplet, which decays to the 3^{+},πf_{7/2}⊗νp_{1/2} ground state. The new half-life corresponds to a pure E2 transition with a strength of 1.93(16) W.u., providing the most precise, unambiguous B(E2) value in the neutron-rich fp region to date for a nucleus with valence protons above Z=20. Notably, it is roughly 4 times larger than the B(E2;1/2^{-}→5/2^{-}) value in ^{55}Ca. The results, as compared to semiempirical and ab initio shell-model calculations, indicate (1) a weak N=34 subshell gap relative to N=32, (2) a large E2 enhancement in Sc as compared to Ca due to 1p-1h proton excitations across Z=28, and (3) empirical effective proton and neutron charges e_{π}=1.30(8)e and e_{ν}=0.452(7)e, respectively, that are in contrast... https://escholarship.org/uc/item/4xx7x4f8 Tue, 28 Apr 2026 00:00:00 +0000 Ogunbeku, TH Allmond, JM Gray, TJ Ong, W-J Brown, BA Gargano, A Grzywacz, R Holt, JD Macchiavelli, AO Miyagi, T Neupane, S Rasco, BC Schatz, H Sherrill, BM Tarasov, OB Arora, H Ayangeakaa, AD Berg, HC Berkman, JM Bleuel, DL Bosmpotinis, K Carpenter, MP Cerizza, G Chester, A Christie, JM Cox, I Crawford, HL https://orcid.org/0000-0002-7765-4235 Crider, BP Davis, J Doetsch, AA Duarte, JG Estrade, A Fijałkowska, A Frantzis, C Gaballah, T Good, EC Haak, K Hanai, S Harke, JT Hartley, AC Hermansen, K Hoff, DEM Hoskins, D Huffman, J Van Isacker, P Jain, R Karny, M King, TT Kitamura, N Kolos, K Laminack, A Liddick, SN Longfellow, B Lubna, RS Lyons, S Madurga, M Mogannam, MJ Owens-Fryar, G Palomino, JR Rajabali, MM Richard, AL Richardson, IJ Ronning, EK Rose, GE https://orcid.org/0000-0002-5645-8905 Ruland, TJ Rykaczewski, KP Scielzo, ND Scriven, DP Seweryniak, D Siegl, K Singh, M Spyrou, A Stepaniuk, M Stuchbery, AE Sweet, A Tripathi, V Tsantiri, A Uthayakumaar, S Walters, WB Watters, S Xu, Z Yokoyama, R https://escholarship.org/uc/item/9t48j8jq We revisit the calculation of the next-to-leading order (NLO) corrections to dijet production in electron-ion collisions at small x. We focus on the back-to-back configuration where the relative transverse momentum P⊥ of the measured jets is much larger than both their momentum imbalance K⊥ and the target saturation momentum Qs(x, A). In this regime, we present for the first time a complete calculation of the real NLO corrections, associated with gluon emissions outside the jet cones, at leading power in 1/P⊥. Our result exhibits TMD factorisation, with the same hard factor as at tree-level and a NLO correction to the Weiszäcker-Williams (WW) gluon transverse momentum dependent (TMD) distribution which involves four Wilson-line operators. By studying different kinematical regimes for K⊥ and for the radiated gluon, we recover all the quantum evolutions that were previously identified for this process at NLO: the B-JIMWLK high-energy evolution and the CSS evolution of the gluon... https://escholarship.org/uc/item/9t48j8jq Fri, 24 Apr 2026 00:00:00 +0000 Caucal, Paul Iancu, Edmond Salazar, Farid Yuan, Feng https://orcid.org/0000-0001-9979-3853 https://escholarship.org/uc/item/64187516 In an experiment performed at the Facility for Rare Isotope Beams (FRIB) using the FRIB Decay Station initiator, 15 new half-lives of isotopes near ^{54}Ca were measured. A new method of extracting lifetimes from experimental data, taking into account the unknown β-delayed neutron emission branches of very neutron-rich nuclei, was developed to enable systematic uncertainty analysis. The experiment observed a dramatic change in the half-life systematics for the isotopes with neutron number N=34. Beyond N=34, the decline of nuclear lifetime is much slower, leading to longer than anticipated lifetimes for near-dripline nuclei. State-of-the-art shell-model calculations can explain the experimental results, revealing the imprint of shell effects and the need for modification of single-particle neutron states. The results from a newly developed quasirandom-phase approximation model with potential for making global predictions were also tested against the experimental results and good... https://escholarship.org/uc/item/64187516 Fri, 24 Apr 2026 00:00:00 +0000 Ong, W-J Xu, ZY Grzywacz, R Ravlić, A Cox, I Allmond, JM King, TT Rasco, BC Rykaczewski, KP Schatz, H Sherrill, BM Tarasov, OB Brown, BA Ajayi, S Arora, H Ayangeakaa, AD Berg, HC Berkman, JM Bleuel, DL Bosmpotinis, K Carpenter, MP Cerizza, G Chester, A Christie, JM Crawford, HL https://orcid.org/0000-0002-7765-4235 Crider, BP Davis, J Doetsch, AA Duarte, JG Estrade, A Fijalkowska, A Frantzis, C Fukushima, K Gaballah, T Gray, TJ Good, E Haak, K Hanai, S Hartley, AC Harke, JT Hermansen, K Harris, C Hausmann, M Hoff, DEM Hoskins, D Huffman, J Jain, R Karny, M Kitamura, N Kolos, K Kwan, E Laminack, A Liddick, SN Longfellow, B Lubna, RS Lyons, S Madurga, M Mogannam, M Neupane, S Nowicki, A Ogunbeku, TH Owens-Fryar, G Palomino, JR Portillo, M Rajabali, MM Richard, AL Richardson, I Ronning, E Rose, GE https://orcid.org/0000-0002-5645-8905 Ruland, T Scielzo, ND Scriven, DP Seweryniak, D Siegl, K Singh, M Smith, MK Spyrou, A Stepaniuk, M Sweet, A Tripathi, V Tsantiri, A Uthayakumaar, S Walters, WB Watters, S Wolinska-Cichocka, M Yokoyama, R https://escholarship.org/uc/item/7wn6x62g The SNO+ Collaboration reports the first evidence of ^{8}B solar neutrinos interacting on ^{13}C nuclei. The charged current interaction proceeds through ^{13}C+ν_{e}→^{13}N+e^{-} which is followed, with a 10 minute half life, by ^{13}N→^{13}C+e^{+}+ν_{e}. The detection strategy is based on the delayed coincidence between the electron and the positron. Evidence for the charged current signal is presented with a significance of 4.2σ. Using the natural abundance of ^{13}C present in the scintillator, 5.7 metric tons of ^{13}C over 231 days of data were used in this analysis. The 5.6_{-2.3}^{+3.0} observed events in the data set are consistent with the expectation of 4.7_{-1.3}^{+0.6} events. This result is the second real-time measurement of CC interactions of ^{8}B neutrinos with nuclei and constitutes the lowest energy observation of neutrino interactions on ^{13}C generally.

Although previous underground experiments have measured this yield across various cosmogenic muon energies, is uniquely positioned due to its exposure to one of the highest average cosmogenic muon energies at 364 GeV. Using ultrapure water, we have determined a neutron yield of at . Comparison with simulations demonstrates clear agreement with the neutron production model, highlighting discrepancies with the widely used 4 model. Furthermore, this measurement reveals a lower cosmogenic neutron yield than that observed by the SNO experiment, which used heavy water under identical muon flux conditions.

A low background search for neutrinoless double beta (0νββ) decay will be conducted using 780 tonnes of liquid scintillator loaded with 3.9 tonnes of natural tellurium, corresponding to 1.3 tonnes of 130Te. This paper provides a general overview of the SNO+ experiment, including detector design, construction of process plants, commissioning efforts, electronics upgrades, data acquisition systems, and calibration techniques.

With low backgrounds and a low energy threshold, the SNO+ collaboration will also pursue a rich physics program beyond the search for 0νββ decay, including studies of geo- and reactor antineutrinos, supernova and solar neutrinos, and exotic physics such as the search for invisible... https://escholarship.org/uc/item/4xb45973 Thu, 23 Apr 2026 00:00:00 +0000 Albanese, V Alves, R Anderson, MR Andringa, S Anselmo, L Arushanova, E Asahi, S Askins, M Auty, DJ Back, AR Back, S Barão, F Barnard, Z Barr, A Barros, N Bartlett, D Bayes, R Beaudoin, C Beier, EW Berardi, G Bialek, A Biller, SD Blucher, E Bonventre, R Boulay, M Braid, D Caden, E Callaghan, EJ Caravaca, J Carvalho, J Cavalli, L Chauhan, D Chen, M Chkvorets, O Clark, KJ Cleveland, B Connors, C Cookman, D https://orcid.org/0000-0001-9385-1194 Coulter, IT Cox, MA Cressy, D Dai, X Darrach, C Davis-Purcell, B Deluce, C Depatie, MM Descamps, F Di Lodovico, F Dittmer, J Doxtator, A Duhaime, N Duncan, F Dunger, J Earle, AD Fabris, D Falk, E Farrugia, A Fatemighomi, N Felber, C Fischer, V Fletcher, E Ford, R Frankiewicz, K Gagnon, N Gaur, A Gauthier, J Gibson-Foster, A Gilje, K González-Reina, OI Gooding, D Gorel, P Graham, K Grant, C Grove, J Grullon, S Guillian, E Hall, S Hallin, AL Hallman, D Hans, S Hartnell, J Harvey, P Hedayatipour, M Heintzelman, WJ Heise, J Helmer, RL Hodak, B Hodak, M Hood, M Horne, D Hreljac, B Hu, J Hussain, SMA Iida, T Inácio, AS Jackson, CM Jelley, NA Jillings, CJ Jones, C Jones, PG https://escholarship.org/uc/item/3x6706z6 We present a novel multimessenger approach to extract the effective radial flow of the quark-gluon plasma (QGP) by jointly analyzing thermal photon and dilepton spectra in heavy-ion collisions. A key feature of this method is that it circumvents the need for a directly unmeasurable reference-the photon temperature in the absence of flow-by establishing, within a calibrated model framework, a stable, approximately linear correlation with the dilepton-inferred temperature. This construction defines an experimentally constructible quantity, v_{r}^{eff}, which reflects early-time collectivity and exhibits a strong correlation with the spacetime-averaged radial velocity of the QGP. Together with previous results linking dilepton slopes to the initial QGP temperature, our work establishes a consistent framework for electromagnetic tomography of the QGP.

Using a multistage Monte Carlo simulation of in-medium jet shower evolution, we explore flavor-dependent medium effects through simulations of inclusive and -tagged jets. The results show that quark jets undergo a nonmonotonic modification compared with gluon jets in observables such as the Pb-Pb to ratio of the soft drop prong angle , the relative prong transverse momentum , and the groomed mass distributions. Due to this nonmonotonic modification, -tagged jets, enriched in quark jets, provide surprisingly clear signals of medium-induced structural modifications, distinct from effects dominated by selection bias. Further systematic studies demonstrate that these effects are dominated by recoil medium response. This work highlights the potential of hard substructures in -tagged jets as powerful tools for probing the jet-medium... https://escholarship.org/uc/item/1gg9n76m Thu, 23 Apr 2026 00:00:00 +0000 Tachibana, Y Sirimanna, C Majumder, A Angerami, A Arora, R Bass, SA Chen, Y Datta, R Du, L https://orcid.org/0000-0002-3029-6602 Ehlers, R https://orcid.org/0000-0002-3897-0876 Elfner, H Fries, RJ Gale, C He, Y Jacak, BV Jacobs, PM https://orcid.org/0000-0001-9980-5199 Jeon, S Ji, Y Jonas, F Kasper, L Kordell, M Kumar, A Kunnawalkam-Elayavalli, R Latessa, J Lee, Y-J Lemmon, R Luzum, M Mak, S Mankolli, A Martin, C Mehryar, H Mengel, T Nattrass, C Norman, J Parker, C Paquet, J-F Putschke, JH Roch, H Roland, G Schenke, B Schwiebert, L Sengupta, A Shen, C Singh, M Soeder, D Soltz, RA Soudi, I Velkovska, J Vujanovic, G Wang, X-N Wu, X Zhao, W https://orcid.org/0000-0001-8324-6134 https://escholarship.org/uc/item/1b56g6sz In this article the authors D.

We explore the sensitivity to different parameterizations of the nucleon-nucleon force, study the convergence pattern in the order-by-order chiral expansion, and estimate remaining uncertainties. Our results are consistent with earlier calculations from pionless effective field theory, offering new insights for a robust uncertainty quantification. Thanks to the order-of-magnitude reduction in uncertainty achieved with chiral effective field theory, the two-photon exchange contribution in electronic deuterium agrees with experimental extractions within 0.5σ, in contrast to the 2.6σ discrepancy observed in muonic deuterium.

In this work, the measured correlation functions for oppositely charged Ξ-K and Ξ − π pairs obtained in high-multiplicity pp collisions at s = 13 TeV at the LHC are presented. For the first time, high-precision data on the Ξ-K interaction are delivered at small relative momenta. The scattering lengths, extracted via the Lednický–Lyuboshits expression of the pair wavefunction, indicate a repulsive and a shallow attractive strong interaction for the Ξ-K and Ξ − π systems, respectively. The Ξ(1620) and Ξ(1690) states are observed in the Ξ − π correlation function and their properties, mass and width, are determined. These measurements are in agreement with other available results. Such high-precision data can help refine the understanding of these resonant states, provide stronger constraints for chirally... https://escholarship.org/uc/item/73q0b8qt Wed, 22 Apr 2026 00:00:00 +0000 Abualrob, IJ Acharya, S Rinella, G Aglieri Aglietta, L Agrawal, N Ahammed, Z Ahmad, S Ahuja, I Akbar, ZUL Akindinov, A Akishina, V Al-Turany, M Aleksandrov, D Alessandro, B Molina, R Alfaro Ali, B Alici, A Alkin, A Alme, J Alocco, G Alt, T Altsybeev, I Andrei, C Andreou, N Andronic, A Andronov, E Angeletti, M Anguelov, V Antinori, F Antonioli, P Apadula, N Appelshäuser, H Arcelli, S Arnaldi, R Arneiro, JGMCA Arsene, IC Arslandok, M Augustinus, A Averbeck, R Azmi, MD Baba, H Babu, ARJ Badalà, A Bae, J Bae, Y Baek, YW Bai, X Bailhache, R Bailung, Y Bala, R Baldisseri, A Balis, B Bangalia, S Banoo, Z Barbasova, V Barile, F Barioglio, L Barlou, M Barman, B Barnaföldi, GG Barnby, LS Barreau, E Barret, V Barreto, L Barth, K Bartsch, E Bastid, N Batigne, G Battistini, D Batyunya, B Bauri, D Alba, JL Bazo Bearden, IG Becht, P Behera, D Behera, S Belikov, I Bella, VD Bellini, F Bellwied, R Beltran, LGE Beltran, YAV Bencedi, G Bensaoula, A Beole, S Berdnikov, Y Berdnikova, A Bergmann, L Bernardinis, L Betev, L Bhaduri, PP Bhalla, T Bhasin, A Bhattacharjee, B Bhattarai, S Bianchi, L Bielčík, J Bielčíková, J Bilandzic, A Binoy, A https://escholarship.org/uc/item/0pk3p7mr In this letter, the first measurement of the femtoscopic correlation of protons and Σ + hyperons is presented and used to study the p– Σ + interaction. The measurement is performed with the ALICE detector in high-multiplicity triggered pp collisions at s = 13 TeV. The Σ + hyperons are reconstructed using a missing-mass approach in the decay channel to p + π 0 with π 0 → γ γ , while both Σ + and protons are identified using a machine learning approach. These techniques result in a high reconstruction efficiency and purity, which allows the measurement of the p– Σ + correlation function for the first time. Thanks to the high significance achieved in the p– Σ + correlation signal, it is possible to discriminate between the predictions of different models of the N–Σ interaction and to accomplish a first determination of the p– Σ + scattering parameters. https://escholarship.org/uc/item/0pk3p7mr Wed, 22 Apr 2026 00:00:00 +0000 Abualrob, IJ Acharya, S Rinella, G Aglieri Aglietta, L Agnello, M Agrawal, N Ahammed, Z Ahmad, S Ahuja, I Akbar, ZUL Akindinov, A Akishina, V Al-Turany, M Aleksandrov, D Alessandro, B Molina, R Alfaro Ali, B Alici, A Alkin, A Alme, J Alocco, G Alt, T Altamura, AR Altsybeev, I Andrei, C Andreou, N Andronic, A Andronov, E Anguelov, V Antinori, F Antonioli, P Apadula, N Appelshäuser, H Arcelli, S Arnaldi, R Arneiro, JGMCA Arsene, IC Arslandok, M Augustinus, A Averbeck, R Azmi, MD Baba, H Babu, ARJ Badalà, A Bae, J Bae, Y Baek, YW Bai, X Bailhache, R Bailung, Y Bala, R Baldisseri, A Balis, B Bangalia, S Banoo, Z Barbasova, V Barile, F Barioglio, L Barlou, M Barman, B Barnaföldi, GG Barnby, LS Barreau, E Barret, V Barreto, L Barth, K Bartsch, E Bastid, N Batigne, G Battistini, D Batyunya, B Bauri, D Alba, JL Bazo Bearden, IG Becht, P Behera, D Behera, S Belikov, I Bella, VD Bellini, F Bellwied, R Beltran, LGE Beltran, YAV Bencedi, G Bensaoula, A Beole, S Berdnikov, Y Berdnikova, A Bergmann, L Bernardinis, L Betev, L Bhaduri, PP Bhalla, T Bhasin, A Bhattacharjee, B Bhattarai, S Bianchi, L Bielčík, J Bielčíková, J Bilandzic, A https://escholarship.org/uc/item/3qt863f0 In this work, we consider the optimization of non-invariant systems with both safety and control constraints. We present a new approach based on Bayesian optimization for the dynamic, safe and controlled optimization of such systems. Although there are other possible use cases, we focus on the application to the electron cyclotron resonance ion source VENUS. From experimental data, we have observed that VENUS behaves to first order as a non-invariant dynamic system with moving areas of instability. Our novel approach aims at providing a tool that can maintain system optimization in a safe way. This is accomplished by making sure the objective function, the beam current in the case of VENUS, does not fall under an operational minimum, while simultaneously requiring the optimization to avoid areas where VENUS is unstable. We compare the result of our approach on synthetic data modeled to mimic the behavior of VENUS with two methods from the literature, a standard Bayesian optimizer... https://escholarship.org/uc/item/3qt863f0 Mon, 20 Apr 2026 00:00:00 +0000 Watson, Victor Campbell, Christopher M https://orcid.org/0000-0003-3577-4316 Crawford, Heather L https://orcid.org/0000-0002-7765-4235 Lai, Yue Shi https://orcid.org/0000-0002-5610-2327 Salathe, Marco https://orcid.org/0000-0003-2484-4606 Todd, Damon https://escholarship.org/uc/item/87x6k0g5 The dependence of f0$$\textrm{f}_{0}$$(980) production on the final-state charged-particle multiplicity is reported for proton–proton (pp) collisions at the centre-of-mass energy, s=$$\sqrt{s}=$$ 13 TeV.

Results are reported for inclusive charged particles, pions, kaons, and protons across various centrality intervals in Pb-Pb collisions at sqrt[s_{NN}]=5.02  TeV, recorded by the ALICE detector. A pseudorapidity-gap technique, similar to that used in anisotropic-flow studies, is employed to suppress short-range correlations. At low p_{T}, a characteristic mass ordering consistent with hydrodynamic collective flow is observed. At higher p_{T} (>3  GeV/c), protons exhibit larger v_{0}(p_{T}) than pions and kaons, in agreement with expectations from quark-recombination models.

To address discrepancies in the literature, the calculation is performed at a heavy pion mass in the limit that the light quark masses are equal to the physical strange quark mass, . Using a state-of-the-art momentum space method, we rule out the presence of a bound di-nucleon in both the isospin 0 (deuteron) and 1 (di-neutron) channels, in contrast with many previous results that made use of compact hexaquark creation operators. To diagnose the discrepancy, we add such hexaquark interpolating operators to our basis and find that they do not affect the determination of the two-nucleon finite-volume spectrum, and thus they do not couple to deeply bound di-nucleons that are missed by the momentum-space operators. Furthermore, we perform a high-statistics calculation of the HAL QCD potential on the same gauge ensembles and find qualitative agreement with our main results.

Applying the light-ray operator product expansion (OPE), we develop a formalism that describes the scaling of the EEC with the input energy Q in the transition and the postconfinement region, where the latter quantum scaling is determined by the J=5 DGLAP anomalous dimension. A key result of our Letter is a novel connection between the light-ray OPE and the dihadron fragmentation function (DFF), where we show that the nonperturbative OPE coefficients correspond to moments of the DFF.

IceCube event selections used to isolate the astrophysical neutrino signal often focus on the morphology of the light patterns recorded by the detector. The analyses presented here use the new IceCube Enhanced Starting Track Event Selection (ESTES), which identifies events likely generated by muon–neutrino interactions within the detector geometry, focusing on neutrino energies of 1–500 TeV with a median angular resolution of 1.4 ° . Selecting for starting-track events filters out not only the atmospheric-muon background but also the atmospheric-neutrino background in the southern sky. This improves IceCube’s muon–neutrino sensitivity to southern-sky neutrino sources, especially for Galactic sources that are not expected to produce a substantial flux of neutrinos above 100 TeV.

In this work, we develop a graph autoencoder as an unsupervised, model-agnostic tool for anomaly detection, using the LHC Olympics dataset as a benchmark. By representing jet constituents as a graph, we introduce a method to systematically control the information available to the model through sparse graph constructions that serve as physically motivated inductive biases. Specifically, (1) we construct graph autoencoders based on locally rigid Laman graphs and globally rigid unique graphs, and (2) we explore the clustering of jet constituents into subjets to interpolate between high- and low-level input representations. We obtain the best performance, measured in terms of the Significance Improvement Characteristic curve for an intermediate level of subjet clustering and certain sparse unique... https://escholarship.org/uc/item/9529n70q Wed, 8 Apr 2026 00:00:00 +0000 Araz, Jack Y Athanasakos, Dimitrios Ploskon, Mateusz https://orcid.org/0000-0003-3161-9183 Ringer, Felix https://escholarship.org/uc/item/6zs3247s ABSTRACT A long-lived central engine embedded in expanding supernova ejecta can alter the dynamics and observational signatures of the event, producing an unusually luminous, energetic, and/or rapidly evolving transient. We use 2D hydrodynamics simulations to study the effect of a central energy source, varying the amount, rate, and isotropy of the energy deposition. We post-process the results with a time-dependent Monte Carlo radiation transport code to extract observational signatures. The engine excavates a bubble at the centre of the ejecta, which becomes Rayleigh–Taylor unstable. Sufficiently powerful engines are able to break through the edge of the bubble and accelerate, shred, and compositionally mix the entire ejecta. The breakout of the engine-driven wind occurs at distinct rupture points, and the outflowing high-velocity gas may eventually give rise to radio emission. The dynamical impact of the engine leads to faster rising optical light curves, with photon escape... https://escholarship.org/uc/item/6zs3247s Mon, 6 Apr 2026 00:00:00 +0000 Eiden, Kiran Kasen, Daniel https://escholarship.org/uc/item/15b5m8k7 Within the Colour Glass Condensate effective theory, we demonstrate that back-to-back dijet correlations in dilute-dense collisions involving a small-x quark from the nuclear target can be factorised in terms of universal transverse momentum dependent distributions (TMDs) for the sea quarks. Two building blocks are needed to construct all these TMDs at the operator level: the sea quark TMD operator which appears in semi-inclusive Deep-Inelastic Scattering (SIDIS) or in the Drell-Yan process and the elastic S-matrix for a quark-antiquark dipole. Compared to SIDIS, the saturation effects are stronger for dijet production in forward proton-nucleus collisions, due to additional scattering in the initial and final state, effectively resulting in a larger value for the nuclear saturation momentum. https://escholarship.org/uc/item/15b5m8k7 Thu, 2 Apr 2026 00:00:00 +0000 Caucal, Paul Morales, Marcos Guerrero Iancu, Edmond Salazar, Farid Yuan, Feng https://orcid.org/0000-0001-9979-3853 https://escholarship.org/uc/item/3071b57v Using the Hydro-Coal-Frag model that combines hydrodynamics at low pT, quark coalescence at intermediate pT, and the LBT transport model at high pT, we study the spectra and elliptic flow of identified hadrons in high multiplicity p–Pb and p–p collisions at the CERN Large Hadron Collider (LHC). In p–Pb collisions, the Hydro-Coal-Frag model gives a good description of the differential elliptic flow over the pT range from 0 to 6 GeV and the approximate number of constituent quark (NCQ) scaling at intermediate pT. Although the Hydro-Coal-Frag model can also roughly describe the elliptic flow in high multiplicity p–p collisions with the quark coalescence process, the larger contribution from the string fragmentations leads to a notable violation of the NCQ scaling of v2 at intermediate pT as observed in the experiment.

The resulting unfolded measurements are straightforward to use for direct comparisons between experiments and a wide variety of theoretical predictions. For decades, popular unfolding strategies were designed to operate on data formatted as one or more binned histograms. In recent years, new strategies have emerged that use machine learning to unfold datasets in an unbinned manner, allowing for higher-dimensional analyses and more flexibility for current and future users of the unfolded data.

However, conventional techniques for EA determination lack the experimental sensitivity to probe very scarce samples. As a result, the EA for the heaviest elements of the periodic table is entirely uncharted. Here, we present a novel technique to determine EAs through Laser Photodetachment Threshold Spectroscopy, performed in an electrostatic ion beam trap to increase the samples’ exposure to laser photons and, thus, improve the experimental signal sensitivity by three orders of magnitude.

Combining all-sky tracks, with superior pointing power and sensitivity in the northern sky, with all-sky cascades, with good energy resolution and sensitivity in the southern sky, we have developed the most sensitive point-source search to date by IceCube that targets the entire sky.

The features, such as the full-energy photopeak, Compton continuum, annihilation peak, and escape peaks, are governed by simple relationships depending on incident energy and have been known for a long time. Monte Carlo computer simulations of gamma rays interacting with a detector will show these features, and with a resolution function applied, the results should look similar to real measurements. The traditional approach to creating a detector response function requires many separate simulations of monoenergetic gamma rays striking the detector.

We employ a dual approach utilizing both measured CCD data and detailed Geant4 simulations. Our analysis compares classical techniques with advanced deep learning methods, including convolutional neural networks (CNNs), autoencoders trained exclusively on tritium data, and preliminary studies on boosted decision trees (BDTs). The CNN, trained on mixed signal/background datasets, demonstrates superior classification performance, while the autoencoder shows the potential of unsupervised, background-agnostic strategies when background characteristics are poorly defined. These results highlight the excellent sensitivity achievable thanks to the background rejection made possible by information-rich CCD data, paving the way for improved portable tritium monitoring. https://escholarship.org/uc/item/8zv4b6qc Wed, 18 Mar 2026 00:00:00 +0000 Rofors, E https://orcid.org/0000-0002-9674-7947 Heller, R https://orcid.org/0000-0002-7368-6723 Cooper, RJ https://orcid.org/0000-0002-5669-2961 Estrada, J Moroni, G Nachman, B Spears, K https://escholarship.org/uc/item/16j1c484 Background: The advent of high-intensity, high-polarization electron beams led to significantly improved measurements of the ratio of the proton’s charge to electric form factors, GEp/GMp.

The task is especially challenging in the case of mobile detector systems because the observed gamma-ray background changes more than for a static detector system, and a pretrained background model can easily find itself out of domain. The result is that algorithms may exceed their intended false alarm rate or sacrifice detection sensitivity to maintain the desired false alarm rate. Non-negative matrix factorization (NMF) is a powerful tool for spectral anomaly detection and identification, but, like many similar algorithms that rely on data-driven background models, in its conventional implementation, it is unable to update in real time to account for environmental changes that affect the background spectroscopic signature.

Among the observations, Zr stands out, as its elemental abundance is difficult to replicate with available i-process models, while the reactions that affect its production through the i process are close enough to stability to study experimentally. Here, we present the experimental constraint of the nuclear level density and γ-strength function (γSF) of Sr91 using the β-Oslo method, which were then input into the TALYS Hauser-Feshbach code to produce the first experimental constraint of the Sr90(n,γ)Sr91 capture reaction. This constraint was used alongside that of Sr92(n,γ)Sr93 for a reduction in the uncertainty of [Y/Zr] production in the i-process relevant environmental neutron... https://escholarship.org/uc/item/33t688z9 Tue, 10 Mar 2026 00:00:00 +0000 Greaves, B Mücher, D Spyrou, A Denissenkov, P Harris, CM Smith, MK Sweet, A Bleuel, DL DeYoung, PA Dombos, AC Gombas, J Good, E Lewis, R Liddick, SN Lyons, SM Naqvi, F Palmisano-Kyle, A Persch, CF Richard, AL Ronning, EK Scielzo, ND Svensson, CE Torode, A von Seeger, WW Wiedeking, M https://orcid.org/0000-0003-4983-3882 Xiao, Y https://escholarship.org/uc/item/2868r9n0 The deformation properties of the low-lying states in Ge74 have been investigated using multistep Coulomb excitation. The measurements were carried out with the advanced γ-ray tracking array, GRETINA, and the CHICO2 particle detector. A comprehensive set of E2 transition and diagonal matrix elements was deduced following an analysis with the semiclassical coupled-channels code GOSIA. The data were compared with results of calculations carried out within the framework of the generalized triaxial rotor model as well as with the configuration interaction shell model and the symmetric rotor model. Results from calculations with covariant density functional theory were used to construct a five-dimensional collective Hamiltonian for further comparisons with the data. Collectively, the calculations provide an accurate reproduction of the experimental matrix elements and further support an understanding in terms of the coexistence of two axially asymmetric shapes.

The results cover the pseudorapidity range |η|<1.1 and constitute the first such measurement performed using a hadronic calorimeter at RHIC. Measurements of dET/dη are presented for a range of centrality intervals and the average dET/dη as a function of the number of participating nucleons, Npart, is compared to a variety of Monte Carlo heavy-ion event generators. The results are in agreement with previous measurements at RHIC, and feature an improved granularity in η and improved precision in low-Npart events. https://escholarship.org/uc/item/9v04g90w Thu, 5 Mar 2026 00:00:00 +0000 Abdulhamid, MI Acharya, U Adams, ER Adawi, G Aidala, CA Akiba, Y Alfred, M Ali, S Alsayegh, A Altaf, S Amedi, H Anderson, DM Andrieux, VV Angerami, A Applegate, N Aso, H Aune, S Azmoun, B Bailey, VR Baranyai, D Bathe, S Bazilevsky, A Bela, S Belmont, R Bennett, J Bernauer, JC Bertaux, J Bi, R Bonenfant, A Boose, S Borchers, C Bossi, H Botsford, R Boucher, R Brahma, A Bryan, JW Cacace, D Cali, I Chamizo-Llatas, M Chauhan, SB Chen, A Chen, D Chen, J Chen, K Chen, KY Cheng, KY Chi, C-Y Chiu, M Clement, J Cline, EW Connors, M Cook, E Corliss, R Morales, Y Corrales Croft, E d'Hose, N Dabas, A Dacosta, D Daradkeh, M Das, SJ Dash, AP David, G Dean, CT Dehmelt, K Dong, X https://orcid.org/0000-0003-3303-0735 Drees, A Durham, JM Enokizono, A Enyo, H Cepero, J Escobar Esha, R Fadem, B Feder, R Finnelli, K Firak, D Francisco, A Frantz, J Frawley, A Fujiki, K Fujiwara, M Garcia, B Garg, P Garmire, G Gentry, E Go, Y Goblin, C Goodman, W Goto, Y Grabas, A Grachov, O Granato, J Grau, N Greene, SV Grossberndt, SK Guidolini-Cecato, R Hachiya, T Haggerty, JS Hamilton, R Hammond, J Hangal, DA https://escholarship.org/uc/item/9hd5v9sb Partonic collectivity is one of the necessary signatures for the formation of quark-gluon plasma in high-energy nuclear collisions. Number of constituent quarks (NCQ) scaling has been observed for hadron elliptic flow v_{2} in top energy nuclear collisions at the Relativistic Heavy Ion Collider and the LHC, and this has been theoretically suggested as strong evidence for partonic collectivity. In this Letter, a systematic analysis of v_{2} of π^{±}, K^{±}, K_{S}^{0}, p, and Λ in Au+Au collisions at sqrt[s_{NN}]=3.2, 3.5, 3.9, and 4.5 GeV, with the STAR experiment at the Relativistic Heavy Ion Collider, is presented. NCQ scaling is markedly violated at 3.2 GeV, consistent with a hadronic-interaction dominated equation of state. However, as the collision energy increases, a gradual evolution to NCQ scaling is observed. This beam-energy dependence of v_{2} for all hadrons studied provides evidence for the onset of dominant partonic interactions by sqrt[s_{NN}]=4.5  GeV. https://escholarship.org/uc/item/9hd5v9sb Thu, 5 Mar 2026 00:00:00 +0000 Aboona, BE Adam, J Adamczyk, L Aggarwal, I Aggarwal, MM Ahammed, Z Alshammri, AK Aschenauer, EC Aslam, S Atchison, J Bairathi, V Bao, X Barish, K https://orcid.org/0000-0003-1461-0726 Behera, S Bellwied, R Bhagat, P Bhasin, A Bhatta, S Bhosale, SR Bielcik, J Bielcikova, J Brandenburg, JD Broodo, C Cai, XZ Caines, H de la Barca Sánchez, M Calderón Cebra, D Ceska, J Chakaberia, I Chaloupka, P Chan, BK Chang, Z Chatterjee, A Chen, D Chen, J Chen, JH Chen, Q Chen, Z Cheng, J Cheng, Y Christie, W Chu, X Corey, S Crawford, HJ Csanád, M Dale-Gau, G Das, A Deppner, IM Deshpande, A Dhamija, A Dimri, A Dixit, P Dong, X https://orcid.org/0000-0003-3303-0735 Drachenberg, JL Duckworth, E Dunlop, JC Engelage, J Eppley, G Esumi, S Evdokimov, O Eyser, O Fatemi, R Fazio, S Feng, Y Finch, E Fisyak, Y Flor, FA Fu, C Fu, T Gagliardi, CA Galatyuk, T Gao, T Geurts, F Ghimire, N Gibson, A Gopal, K Gou, X Grosnick, D Gu, A Gupta, A Hamed, A Hamilton, RJ Han, X Harabasz, S Harasty, MD Harris, JW Harrison-Smith, H Havener, LB He, XH He, Y Herrmann, N Holub, L Hu, C Hu, Q Hu, Y Huang, H Huang, HZ https://orcid.org/0000-0002-6760-2394 Huang, SL Huang, T Huang, Y https://escholarship.org/uc/item/94j36478 The STAR Collaboration reports precise measurements of the longitudinal double-spin asymmetry, , for dijet production with at least one jet at intermediate pseudorapidity in polarized proton-proton collisions at a center-of-mass energy of 200 GeV. This study explores partons scattered with a longitudinal momentum fraction ( ) from 0.01 to 0.5, which are predominantly characterized by interactions between high- valence quarks and low- gluons. The results are in good agreement with previous measurements at 200 GeV with improved precision and are found to be consistent with the predictions of global analyses that find the gluon polarization to be positive.

The data cover the Bjorken x range from 0.20 to 0.83, corresponding to a squared four-momentum transfer Q^{2} range from 2.7 to 11.9  (GeV/c)^{2}, and to an invariant mass W of the final hadronic state greater than 1.84  GeV/c^{2}. The tritium EMC effect measurement is the first of its kind.

In recent years, it has been argued that the NMEs of cMDMs can be related to the third moment of the nucleon's higher-twist (specifically, twist-3) parton distribution function (PDF) , which can, in principle, be measured through dihadron production in semi-inclusive deep inelastic scattering processes. By applying the spin-flavor expansion to the cMDM operators in the large- limit, where is the number of quark colors, we show that the NMEs receive contributions not only from the twist-3 PDF but also from an additional, previously neglected nucleon form factor. Incorporating constraints from the spin-flavor expansion, recent experimental data on , as well as model calculations of , we estimate the NMEs of the cMDM operators.

The EEC is measured both for all the pairs of particles in jets and separately for pairs with like and opposite electric charges.

On an event-by-event basis, the volume of the QGP in ultracentral collisions is mostly constant, while its total entropy can vary significantly due to quantum fluctuations, leading to variations in the temperature of the system. Exploiting this unique feature of ultracentral collisions allows for the interpretation of the correlation of the mean transverse momentum $$(\langle {p}_{\text{T}}\rangle )$$ of produced charged hadrons and the number of charged hadrons as a measure for the speed of sound, cs. This speed is related to the rate at which compression waves travel in the QGP and is determined by fitting the relative increase in $$\langle {p}_{\text{T}}\rangle $$ with respect to the relative change in the average charged-particle density $$(\langle \text{d}{N}_{\text{ch}}/\text{d}\eta \rangle )$$ measured at mid-rapidity.

Charged hadron yields are extracted by counting cluster pairs in the inner and outer layers of the Intermediate Silicon Tracker, with corrections applied for detector acceptance, reconstruction efficiency, combinatorial pairs, and contributions from secondary decays. The measured distributions cover |η| < 1.1 across various centralities, and the average pseudorapidity density of charged hadrons at mid-rapidity is compared to predictions from Monte Carlo heavy-ion event generators.

In this assessment, the fission product Nb98 was assigned the highest priority for study by total absorption spectroscopy due to its large cumulative fission branching fraction and because the β-decay data from several experiments are discrepant. Purpose: To obtain the complete β-decay feeding pattern of Nb98 and determine the impact on the average γ energy per Nb98β decay and ν¯e emission calculations. The complete 98Nb β-decay feeding pattern includes ground-state to ground-state β feeding and direct β feeding to the 0+ first-excited state (both have no associated γ rays), and the ground-state to excited-state β transitions followed by γ transitions to the ground state of the daughter nucleus, Mo98.

The polarizations of Λ and Λ ¯ are found to be consistent with each other, indicating little contribution of the spin-magnetic coupling to the measured polarization. Comparison to previously measured polarization in Au+Au collisions show no obvious system size dependence. The results are qualitatively consistent with hydrodynamic calculations including contributions from shear-induced polarization and thermal vorticity. For the first time in heavy-ion collisions, the dependence of the global polarization on the hyperon’s... https://escholarship.org/uc/item/1rv0m82m Wed, 4 Mar 2026 00:00:00 +0000 Aboona, BE Adam, J Agakishiev, G Aggarwal, I Aggarwal, MM Ahammed, Z Aitbayev, A Alekseev, I Alpatov, E Alshammri, AK Aparin, A Aslam, S Atchison, J Averichev, GS Bairathi, V Bao, X Barik, P Barish, K https://orcid.org/0000-0003-1461-0726 Behera, S Bhagat, P Bhasin, A Bhatta, S Bordyuzhin, IG Brandenburg, JD Brandin, AV Broodo, C Cai, XZ Caines, H de La Barca Sánchez, M Calderón Cebra, D Ceska, J Chakaberia, I Chang, YS Chang, Z Chatterjee, A Chen, D Chen, JH Chen, Q Chen, W Chen, Z Cheng, J Cheng, Y Christie, W Chu, X Corey, S Crawford, HJ Csanad, M Dale-Gau, G Das, A Dedovich, TG Deppner, IM Derevschikov, AA Deshpande, A Dhamija, A Dimri, A Dixit, P Dong, X https://orcid.org/0000-0003-3303-0735 Drachenberg, JL Duckworth, E Dunlop, JC El-Feky, YS Engelage, J Eppley, G Esumi, S Evdokimov, O Eyser, O Fan, B Fatemi, R Fazio, S Feng, H Feng, Y Finch, E Fisyak, Y Flor, FA Fu, C Fu, T Gao, T Gao, Y Geurts, F Gibson, A Gopal, K Gou, X Grosnick, D Gu, A Gupta, A Guryn, W Hamed, A Hamilton, RJ Han, J Han, X Harasty, MD Harris, JW Harrison-Smith, H Havener, LB He, XH He, Y Hu, C Hu, Q Hu, Y Huang, H
