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.

Calculation of Particle Pair Correlation Functions with Classical Trajectory Approximation

This paper presents a novel Monte Carlo model using a classical trajectory approximation to calculate particle pair correlation functions in heavy-ion collisions, demonstrating that the method successfully fits experimental data and is highly sensitive to the source's spatio-temporal extent while being largely independent of the temperature parameter, thus advancing femtoscopic interferometry in the Fermi energy domain.

Maximally Symmetric Boost-Invariant Solutions of the Boltzmann Equation in Foliated Geometries

This paper presents a unified exact solution to the relativistic Boltzmann equation for a boost-invariant conformal gas on dS3×RdS_3 \times \mathbb{R} across all constant-curvature slicings, which reproduces known Bjorken and Gubser flows while introducing a novel analytic "Grozdanov flow" for hyperbolic foliations that naturally encompasses both hydrodynamic and free-streaming regimes.

Gamma-ray Signatures of r-Process Radioactivity from the Collapse of Magnetized White Dwarfs

This paper predicts that the accretion-induced collapse of magnetized white dwarfs produces distinctive gamma-ray signatures from both r-process and iron-peak nuclei, which planned MeV gamma-ray telescopes could detect out to distances of approximately 30 Mpc, thereby offering a unique observational method to distinguish these events from binary neutron star mergers.

DIS dijet production in Background Field Approach: General formalism and methods

This paper develops a general formalism for computing physical observables in the background field approach by representing propagators as path-ordered exponents, applying it to DIS dijet production to derive a cross section valid in arbitrary kinematics and demonstrating its consistency with known results in both back-to-back and small-xx limits while providing a quantitative matching between these regimes.

Mass measurements of 179−184^{179-184}Yb identify an anomalous proton-neutron interaction

This paper reports the first mass measurements of neutron-rich ytterbium isotopes (179−184^{179-184}Yb), revealing an anomalously strong proton-neutron interaction in the "hole-hole" regime below 208^{208}Pb that challenges current mean-field models and aids in refining predictions for the N=126N=126 r-process waiting point.

JLab and J-PARC for the J/{\ensuremath{\psi}} Production at the Threshold

This paper synthesizes new threshold measurements of J/ψJ/\psi production from JLab experiments (007 and CLAS12) with previous GlueX data to confirm a consistent phenomenological determination of the J/ψJ/\psi-proton scattering length, while highlighting how upcoming J-PARC measurements will further clarify the systematic trend of vector meson-nucleon interactions predicted by the "young vector meson" hypothesis.

The eikonal spin-dependent Odderon and gluon Sivers function of a proton, and its small-xx evolution

This paper utilizes a three-quark light-front model to calculate the gluon Sivers function of a proton at moderately small xx and numerically determines its small-xx evolution via the BFKL anomalous dimension, revealing a power-law tail behavior of k⊥−3.3k_\perp^{-3.3} at high transverse momentum.
