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 introduces full configuration interaction quantum Monte Carlo (FCIQMC) as a novel, accurate stochastic solver for nuclear structure calculations, demonstrating its capability to compute ground-state properties of light nuclei with sub-percent uncertainties and treat systems beyond the reach of conventional methods.
This paper introduces an interpretable multitask deep-learning framework that analyzes transverse momentum distributions from ultra-peripheral collisions to simultaneously extract multiple nuclear-structure indicators, such as deformation and neutron skin, by disentangling diffraction and interference patterns in coherent photoproduction.
This paper reviews the fundamentals and significance of flavor-diagonal hadronic CP violation in the search for new physics, summarizes recent progress in quantifying its contribution to observables like electric dipole moments and beta decay correlations, and discusses current approaches to solving the strong CP problem without introducing additional fields.
This paper presents an updated extraction of unpolarized quark transverse momentum distributions in the pion by incorporating a more comprehensive treatment of theoretical uncertainties and, for the first time, investigating flavor-dependent differences using all available unpolarized pion-nucleus Drell-Yan data.
This paper proposes that an enhanced isovector tensor coupling within covariant density-dependent point-coupling energy density functionals naturally induces a strong isovector spin-orbit interaction, offering a relativistic mechanism to simultaneously resolve the tensions between PREX-II and CREX parity-violating electron scattering data while maintaining accurate descriptions of nuclear properties.
This paper details the construction, characterization, commissioning, and beam test performance of 15 Silicon Tracking System modules, originally developed for the FAIR-CBM experiment, which were installed and operated in the J-PARC E16 experiment to search for chiral symmetry restoration signatures.
This paper presents the first unambiguous evidence of parton energy loss (jet quenching) in oxygen-oxygen collisions at TeV, demonstrated by a significant suppression of the double ratio at a level that cannot be explained by cold nuclear matter effects alone.
The ALICE Collaboration presents the first measurements of -tagged jet angularities in proton-proton collisions at TeV, providing evidence for the QCD dead-cone effect by demonstrating that charm-quark-initiated jets exhibit suppressed collinear radiation compared to inclusive jets, thereby establishing a crucial baseline for future heavy-ion studies.
The ALICE Collaboration presents the first measurements of jet-energy flow in Pb-Pb collisions at 5.02 TeV, revealing a significant suppression of energy flow at larger radii compared to pp collisions that indicates jet narrowing and is best described by the JEWEL model without recoil, while models incorporating medium response are disfavored by the data.
This paper reports high-precision measurements of the masses of the and baryons and their antiparticles using ALICE data from LHC proton-proton collisions, achieving fractional uncertainties of approximately 60 parts per million to establish new benchmarks for strange-baryon spectroscopy, test CPT invariance, and significantly reduce scale uncertainties in lattice QCD calculations.
