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.
Based on the first measurement of hypertriton production in proton-proton collisions at the LHC, this study confirms the hypertriton's halo structure and estimates the hyperon's separation from its deuteron core to be approximately 9.54 fm using the nuclear coalescence framework.
The ALICE collaboration reports the first measurement of charged-particle dijet invariant mass spectra in pp and p-Pb collisions at 5.02 TeV, finding a nuclear modification factor consistent with unity that suggests the low-mass region is sensitive to subtle anti-shadowing effects currently below experimental sensitivity.
This paper presents measurements of prompt and non-prompt J/ production yields at midrapidity in 13 TeV pp collisions, revealing a stronger-than-linear increase in self-normalized yields with charged-particle multiplicity that varies depending on the azimuthal region relative to the J/ momentum.
This chapter provides an introductory overview of relativistic mean-field models, detailing their theoretical foundations and applications in constructing equations of state for dense neutron-rich matter to bridge nuclear experiments with astrophysical observations of neutron stars.
Using the CMS detector, this study presents the first measurements of correlations among mixed-order moments of two and three flow harmonics in XeXe and PbPb collisions, leveraging the distinct nuclear shapes of doubly-magic Pb and triaxially deformed Xe to probe initial-state geometry fluctuations and constrain the nonlinear hydrodynamic response of the quark-gluon plasma.
This paper applies radiative corrections to recent MINERvA antineutrino-hydrogen scattering data to extract the nucleon axial-vector form factor and radius, thereby enabling more precise comparisons with lattice QCD predictions and reducing uncertainties in neutrino interaction modeling.
This paper presents a fast, high-fidelity generative model based on score-driven diffusion and the Point-Edge Transformer architecture that successfully simulates realistic, high-multiplicity heavy-ion collision events through a two-stage training strategy, demonstrating its potential to replace computationally intensive traditional simulations.
This paper evaluates pion-induced QED radiative corrections to the inverse beta decay cross section using heavy baryon chiral perturbation theory, demonstrating that these effects are small enough to enable sub-permille theoretical precision for antineutrino energies above 10 MeV.
This paper presents recent ALICE measurements from July 2025 LHC runs involving proton-oxygen, oxygen-oxygen, and neon-neon collisions, detailing charged-particle pseudorapidity densities, flow coefficients, and neutral pion suppression to advance the understanding of particle production and collective phenomena in small collision systems.
This paper calculates next-to-leading order nuclear matrix elements for two-neutrino double-beta decay to excited states in key isotopes using the nuclear shell model, finding that while NLO corrections are typically small, they can become significant due to leading-order cancellations, and that nuclear deformation and seniority structure critically influence the predicted half-lives.
