This paper reviews the current status and theoretical understanding of charmonium production in low-energy nuclear collisions at SPS, Fermilab, and HERA facilities, while outlining future prospects for measurements near the kinematic threshold in the upcoming CBM and NA60+ experiments.
This overview summarizes novel theoretical and experimental advances, particularly data from the INDRA-FAZIA collaboration and calculations from the BUU transport model, to constrain the density dependence of the nuclear symmetry energy via isospin transport in heavy-ion collisions within the Fermi energy range.
This paper reports the first detection of marine microseismic vibrations using mK-scale calorimeters in the CUORE experiment, demonstrating their seasonal impact on detector performance and validating a noise decorrelation algorithm to mitigate such environmental noise for future rare-event searches.
Using 1.93 nb of Pb+Pb collision data at TeV, the ATLAS collaboration presents the first differential fiducial measurements of production and extracts constraints on the -lepton's anomalous magnetic and electric dipole moments, marking the first time the latter has been measured in heavy-ion collisions.
This paper demonstrates that machine learning models trained on high-fidelity simulated gamma spectroscopy data can accurately classify and estimate the fission yields of very low-yield nuclear tests, offering a viable technical solution for verifying the Comprehensive Nuclear-Test-Ban Treaty's zero-yield standard.
This contribution presents an extended plain-text syntax for Geant4 that integrates optical properties via new ":prop" and ":surf" tags, enabling users to configure and execute complex optical simulations without writing C++ code.
This study employs high-level relativistic coupled-cluster calculations to determine critical atomic properties of the Th ion, enabling precise estimates of nuclear charge radii and moments while simultaneously revealing significant higher-order relativistic effects that are essential for advancing nuclear clock technology and fundamental physics research.
This study validates the use of Monte Carlo simulations to demonstrate that magnetite aggregates provide superior neutron shielding efficacy with shorter attenuation lengths compared to conventional high-density concrete, offering critical insights for optimizing radiation shielding designs in proton therapy facilities.
This paper presents new measurements of the transverse momentum, rapidity, and centrality dependence of hypertriton () production yields in Au+Au collisions at = 3 to 7.7 GeV from the STAR BES-II experiment, comparing these results with phenomenological models to discuss the underlying production mechanisms.
This paper presents a precise determination of the strong coupling constant through a global fit of heavy jet mass data, utilizing state-of-the-art theoretical predictions that combine fixed-order calculations, multiple resummation orders, and first-principles power corrections to demonstrate the critical role of resummation in achieving robust results and revealing evidence for negative power corrections in the trijet region.
