Nucl-Ex represents the dynamic frontier where scientists probe the fundamental building blocks of matter through high-energy experiments. By smashing particles together at incredible speeds or observing rare cosmic events, researchers uncover the forces that govern our universe and test the limits of our current understanding of physics.
At Gist.Science, we ensure these breakthroughs reach a broader audience by processing every new preprint in this field directly from arXiv. For each study, we provide both a clear, plain-language explanation of the core discoveries and a detailed technical summary for those seeking deeper insights. Below are the latest papers in nuclear experiment research, curated to help you stay informed on the latest developments from the lab.
This paper evaluates non-negligible QED nuclear medium effects on various scattering processes at the future Electron-ion collider in China (EicC), presenting first-order opacity expansion calculations and the first computations for charged-current deep inelastic and polarized scattering across heavy and light nuclei to highlight their importance for extracting nucleon structure.
This paper demonstrates that the extraction of nuclear surface diffuseness from relativistic heavy ion collisions is fundamentally limited by strong geometric degeneracies between the surface parameter and intrinsic nuclear deformations, though multiparticle triangular correlations offer a more independent pathway to constrain these properties.
This paper presents and validates a machine-learning-based Boosted Decision Tree algorithm for the CLAS12 experiment that effectively identifies electrons and positrons while significantly reducing charged-pion contamination, achieving over 90% lepton retention in simulated samples and demonstrating reliability on experimental data.
This paper analyzes net-proton cumulants in Au+Au collisions using finite-size scaling to identify a potential QCD critical point near MeV, but concludes that while the observed scaling patterns are consistent with criticality, they are not yet definitive evidence due to similar behaviors arising from non-critical dynamical simulations and experimental acceptance effects.
This paper presents recent results on strange hadron production in Au+Au collisions at = 3.2–4.5 GeV from the STAR Beam Energy Scan phase-II program, analyzing transverse momentum spectra, rapidity densities, and centrality dependence to compare with higher-energy data and transport model calculations for insights into baryon-rich nuclear matter.
This white paper outlines the LUNE experiment at the HIAF facility, which aims to utilize high-intensity muon beams to resolve fundamental questions in nuclear and particle physics, including the proton charge radius puzzle and nucleon structure, through a two-phase program of precision elastic and inelastic scattering measurements.
The LHCb experiment reports the first measurement of the -to- production cross-section ratio in and $pp$ collisions at using SMOG2, observing a ratio of in collisions that signals the emergence of nuclear effects and establishes a baseline for future studies with larger collision systems.
This paper reports the successful fabrication and characterization of a 20-gram, wingless, p-type inverted coaxial point-contact HPGe detector featuring thin amorphous-germanium contacts, which demonstrated stable sub-picoFarad operation, low leakage current, and high energy resolution while confirming sensitivity to near-surface interactions.
This paper presents an impact-parameter dependent perturbative QCD model based on the Color Glass Condensate framework, which successfully describes a wide range of combined HERA data at small- by incorporating an analytical solution to the Balitsky-Kovchegov equation and an exponential saturation momentum profile consistent with the Froissart theorem.
This paper re-evaluates Doppler-shift attenuation method (DSAM) lifetime measurements in Cr using contemporary stopping powers instead of historical LSS theory, resulting in increased lifetimes that align better with shell-model calculations and suggest a revision of the spin assignments for the 3.786 MeV and 4.043 MeV levels.
