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.

Glauber-theory calculations of high-energy nuclear scattering observables using variational Monte Carlo wave functions

This paper presents ab initio Glauber theory calculations for high-energy nuclear scattering observables in p+12C, 12C+12C, and 6He+12C systems using variational Monte Carlo wave functions, demonstrating excellent agreement with experimental data and revealing that the cumulant expansion of the phase-shift function converges rapidly up to the second order.

Bayesian Constraints on the Neutron Star Equation of State with a Smooth Hadron-Quark Crossover

This paper employs Bayesian inference within a unified framework to constrain the neutron star equation of state across hadronic, crossover, and quark phases, revealing that current multi-messenger data strongly limit low-to-intermediate density nuclear symmetry energy parameters while leaving high-density quark matter properties largely unconstrained until next-generation observations become available.

Investigation of Nonlinear Collective Dynamics in Relativistic Heavy-Ion Collisions Using A Multi-Phase Transport Model

Using the AMPT model, this study demonstrates that while the nonlinear response coefficient χ4,22\chi_{4,22} grows dynamically during the evolution of relativistic heavy-ion collisions, the ratio of this coefficient between U+U and Au+Au systems remains stable across all stages, effectively isolating intrinsic initial-state geometric correlations to support experimental efforts in extracting high-order nuclear structure.

Observation of impact parameter dependent modifications of nuclear parton distributions in photonuclear Pb+Pb collisions at sNN=5.02\sqrt{s_\mathrm{NN}} = 5.02 TeV with the ATLAS detector

Using 2018 ATLAS data from ultra-peripheral Pb+Pb collisions at 5.02 TeV, this study provides the first experimental observation that nuclear parton distribution modifications vary with impact parameter, evidenced by a significant difference in γ+A\gamma+A jet production cross-sections between collisions with and without forward neutron emission.
