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.

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.

Microscopic Investigation of Fusion and Quasifission Dynamics

This paper applies Time-Dependent Hartree-Fock theory to investigate fusion and quasifission dynamics in heavy-ion reactions relevant to superheavy element production, demonstrating reasonable agreement with experimental data for 48^{48}Ca+238^{238}U fusion and revealing the significant impact of tensor forces on shell effects in 48^{48}Ca+249^{249}Bk quasifission.

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.

Does hot QCD have a conformal manifold in the chiral limit?

Based on recent lattice evidence and 't Hooft anomaly constraints, this paper proposes that the chiral phase transition in hot QCD for Nf≥2N_f \ge 2 massless flavors may be described by a conformal manifold of θB\theta_B-dependent universality classes featuring an exactly marginal operator related to baryon density, rather than a standard Ginzburg-Landau critical point.

Shear Viscosity and Electrical Conductivity of Rotating Nuclear Medium in Hadron Resonance Gas and Nambu-Jona Lasinio Models

This paper investigates how rotation influences the anisotropic shear viscosity and electrical conductivity of strongly interacting matter by employing kinetic theory within Hadron Resonance Gas and Nambu-Jona-Lasinio models, revealing that rotation suppresses chiral condensates, generates a sizable Hall-like conductivity, and reduces transport coefficients relative to isotropic cases.
