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 presents an analytic probabilistic description of ultra-high-energy cosmic ray interactions, modeling them as Markov jump processes to overcome the limitations of current deterministic and Monte Carlo approaches in accurately characterizing nuclear cascades and their impact on observed cosmic ray composition and spectrum.
Using chiral perturbation theory, this study derives the one-pion exchange potential in strong magnetic fields, revealing that the potential's range decreases in all directions and induces a deuteron energy shift comparable to its binding energy at field strengths around the pion-mass scale.
Using a complex-energy approach and direct time propagation, this study investigates the ill-defined radius of proton resonances, revealing an early-time plateau where the Gamow resonance radius matches experimental values and demonstrating a nonmonotonic dependence on decay energy that includes a halolike charge radius enhancement across the threshold.
This study utilizes PYTHIA8 simulations to investigate the correlation between prompt and nonprompt production and transverse spherocity in 13 TeV $pp$ collisions, demonstrating how this event-shape observable can distinguish hard QCD processes from underlying events influenced by multiple parton interactions.
This study proposes that medium vorticity induces spin-dependent dissociation of quarkonia via a modified color-singlet potential, thereby altering their spin alignment () in Pb--Pb collisions at TeV and offering new insights into the microscopic dynamics of the vortical quark-gluon plasma.
This article reviews recent R&D efforts in Cherenkov imaging technologies, highlighting advances in sensor technology, radiator materials, and photon timing that address growing demands for momentum coverage, precision, and radiation tolerance in future particle and nuclear physics experiments.
This paper presents the first differential measurements of deuteron production spectra in inelastic p+p collisions at 158 GeV/c by the NA61/SHINE experiment, providing essential data to refine models of cosmic antinuclei production for dark matter searches.
By combining total absorption -spectroscopy and -delayed neutron emission data to constrain ground-state to ground-state -decay strengths of neutron-rich nuclei near the island of inversion, this study reveals weaker transitions than previously predicted, indicating reduced neutrino cooling efficiency in accreted neutron star crusts.
This paper presents the first direct measurement of radial flow in Pb-Pb collisions at 5.02 TeV using the novel observable , revealing mass ordering at low transverse momentum and quark recombination effects at high momentum that confirm the sensitivity of this probe to collective expansion and hadronization dynamics in the quark-gluon plasma.
This paper presents projected sensitivity estimates showing that the KATRIN experiment, utilizing its upcoming TRISTAN detector upgrade, will be capable of probing keV-scale sterile neutrino mixing amplitudes down to for masses between 4 and 13 keV, significantly extending the reach of previous laboratory searches despite potential systematic uncertainties.
