Nuclear theory sits at the fascinating intersection of particle physics and the forces that hold our universe together. This field explores how protons and neutrons bind inside atomic nuclei, seeking to understand the fundamental interactions that govern matter at its most dense and energetic levels. While the mathematics involved can be incredibly complex, the core questions are deeply human: how does the universe function at its smallest scales, and what happens when we push matter to its limits?

At Gist.Science, we make these cutting-edge discoveries accessible by processing every new preprint published in this category on arXiv. Our team transforms dense academic manuscripts into clear, plain-language summaries alongside detailed technical overviews, ensuring that both experts and curious readers can grasp the latest breakthroughs without getting lost in the jargon. Below are the latest papers in nuclear theory, distilled and ready for you to explore.

System-size dependence of strangeness production from p+p to Pb+Pb: quantitative tests of the K+/π+K^+/\pi^+ horn

This study quantitatively evaluates various theoretical frameworks against K+/π+K^+/\pi^+ data across the full NA61/SHINE system-size ladder, revealing that no single model explains the entire dataset but that a combination of core-corona and canonical statistical models successfully describes the observed step-like enhancement of strangeness production and the "horn" structure in heavy-ion collisions.

Hadronic rescattering effects on net-proton cumulants from functional renormalization group calculations

This study demonstrates that hadronic rescattering significantly suppresses higher-order net-proton cumulant signals, particularly the C4/C2C_4/C_2 ratio, during the late-stage evolution of heavy-ion collisions, necessitating its inclusion as a non-negligible background when extracting QCD critical endpoint signatures from experimental data.

Spin-State Teleportation and Tests of EPR Correlations Using 151 MeV Entangled Protons

This paper proposes a feasible scheme for quantum spin-state teleportation and tests of EPR correlations using 151 MeV entangled protons produced via exclusive proton-deuteron breakup, demonstrating that the polarization of a target proton can be transferred to a distant entangled partner and that scattering one member of a Bell-state pair induces identical polarization in the other.

N3^{\mathbf{3}}LL + O(αs2)\mathcal{O}(\alpha_s^2) predictions of lepton-jet azimuthal angular distribution in deep-inelastic scattering

This paper presents next-to-next-to-next-to-leading logarithmic (N3^{3}LL) resummation combined with O(αs2)\mathcal{O}(\alpha_s^2) fixed-order corrections to predict lepton-jet azimuthal angular distributions in deep-inelastic scattering, offering a precision framework for probing the nucleon's three-dimensional structure and analyzing data from HERA and future electron-ion collider experiments.

Simulated-Annealing Optimization of Mean-Field Parameters in a Correlated-Basis Nuclear Model with Realistic Short-Range Correlations

This study demonstrates that optimizing a six-parameter Woods-Saxon mean field within a correlated-basis framework is essential for accurately reproducing nuclear charge radii and generating the high-momentum strength observed in elastic form factors, as failing to refit parameters when introducing explicit short-range correlations leads to significant errors.
