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.
This paper implements and analyzes two distinct gauge field flow constructions—gradient flow decoupling and equation-of-motion (EOM) flow—for chiral gauge theories formulated with domain wall fermions on a lattice slab, demonstrating how these methods successfully preserve current conservation and realize anomaly inflow in the presence of background gauge fields.
This paper presents a reply to a comment regarding the partial conservation of seniority in semi-magic nuclei, addressing the specific points raised in the June 2026 arXiv submission.
This paper establishes a non-perturbative light-front framework to define and compute spin-orbit correlation distributions in charmonium and mesons via the parity-odd energy-momentum tensor, revealing that these observables provide rich, non-trivial insights into partonic dynamics even in systems with zero total angular momentum.
Using the Chapman-Enskog method within kinetic theory, this paper derives first- and second-order dissipative relativistic hydrodynamic equations for a multi-component quark-gluon plasma with baryon, electric, and strangeness charges, explicitly calculating the temperature and chemical potential dependence of the resulting diffusion matrix elements and their ratio to shear viscosity.
By performing Bayesian inference on neutron star data from gravitational waves and X-ray observations alongside theoretical constraints from chiral effective field theory and perturbative QCD, this study finds evidence favoring a strong first-order phase transition in dense matter that likely occurs above the central density of the most massive neutron stars, thereby reconciling the need for a stiff equation of state with asymptotic softening.
This study presents the first systematic analysis of rigidly rotating protoquark stars within the density-dependent quark mass framework, revealing that thermal evolution and rapid rotation significantly enhance stellar stability and deformation, thereby creating distinct observational signatures that future multimessenger data must account for to robustly identify quark matter in compact stars.
This paper compares theoretical calculations of inelastic polarized proton scattering from O exciting levels with available experimental data to investigate the roles of antisymmetrization and pion condensation, while noting that further data is required to draw definitive conclusions.
This paper utilizes the SFitter global analysis framework within an effective quantum field theory approach to interpret current permanent electric dipole moment (EDM) measurements via a hadronic-scale Lagrangian, revealing that while some parameters are well-constrained, others require more high-precision data and that theory uncertainties can be managed within the analysis.
This paper argues that hybrid stars are unlikely candidates for observed mass-gap compact objects because Bayesian analysis of modern mass-radius constraints favors equations of state with deconfinement occurring around , which would produce twin stars that effectively rule out hybrid stars in the mass gap.
This paper presents the first NNLL collinear resummation of projected -point energy correlators up to matched to NLO fixed-order predictions, achieved by computing new two-loop jet functions and incorporating leading non-perturbative corrections, thereby establishing quantitative control over these observables for future precision extractions.
