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.

Limits on the chiral magnetic effect from the event shape engineering and participant-spectator correlation techniques in Pb-Pb collisions at sNN=5.02\sqrt{s_{\rm NN}} = 5.02 TeV

This paper presents the latest ALICE results from Pb-Pb collisions at sNN=5.02\sqrt{s_{\rm NN}} = 5.02 TeV, utilizing event shape engineering and participant-spectator correlation techniques to measure charge-dependent correlations and establish upper limits consistent with the absence of a Chiral Magnetic Effect signal.

Understanding the impact of nuclear effects on proton decay searches with the GiBUU model

This study utilizes the GiBUU framework to demonstrate that while pion final-state interactions have a moderate impact on proton decay search sensitivity in water Cherenkov detectors, the choice of Fermi momentum distribution constitutes the dominant systematic uncertainty affecting atmospheric neutrino background estimates.

Universal and non-universal finite-volume effects in the vicinity of chiral phase transition in (2+1)-flavor QCD

This paper presents a finite-size scaling analysis of the chiral order parameter in (2+1)-flavor QCD using HISQ lattice data, demonstrating that infinite-volume extrapolated results align with expected O(2)O(2) scaling behavior while quantifying finite-size deviations to improve the precision of chiral phase transition temperature determinations.

Opportunities for Imaging Light Nuclei with a Second Interaction Region at the Electron-Ion Collider

This paper presents an exploratory study demonstrating how a proposed second interaction region at the Electron-Ion Collider, featuring enhanced forward acceptance, would enable the detection of intact light nuclei to map their spatial parton distributions through coherent diffractive processes.

Near-Threshold J/ψ→μ+μ−ψ\to μ^+μ^- Photoproduction and the Gluonic Gravitational Form Factors of the Proton

This paper reports the measurement of near-threshold J/ψ→μ+μ−J/\psi \to \mu^+\mu^- photoproduction cross sections from the J/ψ\psi-007 experiment at Jefferson Lab, which, when combined with electron decay data and analyzed via Holographic QCD, yields precise constraints on the proton's gluonic gravitational form factor Cg(t)\mathcal{C}_g(t) that agree with lattice QCD calculations and support a spatial picture of gluon dominance at larger radii with confining inward pressure.

Probing in-medium effect via giant dipole resonance in the extended quantum molecular dynamics model

This study employs a stochastic approach within the extended quantum molecular dynamics model to demonstrate that the peak position and width of the giant dipole resonance in 208{}^{208}Pb are highly sensitive to the symmetry energy and in-medium nucleon-nucleon cross sections, thereby offering a pathway to constrain the nuclear equation of state and confirming that a significant reduction of free cross sections in the medium is necessary to accurately reproduce experimental data.

Probing Neutron Skins with KDAR Neutrinos: From Coherent to Diffractive Elastic Neutrino--Nucleus Scattering

This paper demonstrates that kaon-decay-at-rest (KDAR) neutrinos enable coherent elastic neutrino-nucleus scattering measurements to extend beyond the strict coherent limit into the diffractive regime, offering a competitive and complementary method to electron scattering for precisely probing neutron skin thickness in various nuclei.

Searches for axion-like particles in proton-proton and ion-ion collisions at energies in the center of mass system of 5.02 TeV and 13 TeV

This paper presents a theoretical modeling of axion-like particle production and decay into photons in proton-proton and lead-lead collisions at 5.02 TeV and 13 TeV, utilizing Good-Walker eigenstate models to calculate cross-section dependencies on collision energy, ALP mass, and event numbers based on ATLAS light-by-light scattering data.

Evidence of medium response to hard probes using correlations of Z bosons with hadrons in heavy ion collisions

This paper presents the first evidence of medium response to hard probes in heavy ion collisions by observing significant modifications in the distributions of low transverse momentum hadrons recoiling against Z bosons in lead-lead collisions, consistent with theoretical predictions of a hydrodynamic wake generated by energy depletion in the quark-gluon plasma.
