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 analyzes nuclear matter properties and neutron star structures using an extended linear sigma model, demonstrating that the introduction of the meson creates a plateau in symmetry energy consistent with experimental constraints, while a negative pion-nucleon sigma term is required to achieve a stiff equation of state capable of supporting massive neutron stars.
This paper employs SU(2) chiral perturbation theory with isospin-breaking effects to derive the QCD -vacuum solution and compute the temperature dependence of topological observables and domain wall tension up to next-to-leading order, revealing distinct monotonic behaviors for different cumulants and providing crucial theoretical insights for axion physics in hot QCD matter.
This paper develops a quantum kinetic theory for Quantum Chromodynamics that incorporates leading-order collision terms to reproduce the Boltzmann equation at lowest order and predict spin polarization of quarks and gluons at next order, revealing distinct behaviors for vortical versus non-vortical gradients and a mechanism for spin-orbital angular momentum conversion via inelastic collisions.
This chapter reviews the similarity renormalization group method for nuclear forces, detailing its flow equations, diagonalization mechanism, and induced many-body interactions to highlight its role in advancing first-principles nuclear calculations.
This study utilizes Light-Front Holographic QCD and gauge/string duality to establish a unified framework for extracting quark and gluon distributions and form factors, while demonstrating that the trace anomaly contributes approximately 23% to the proton mass through the analysis of near-threshold production.
This paper identifies fluorine-based compounds, particularly octafluoropropane, as optimal targets for measuring subleading axial-vector contributions in coherent elastic neutrino-nucleus scattering, demonstrating that such experiments could determine the axial coupling at the level and probe spin-dependent new physics.
Using a coupled-channels framework derived from a constituent quark model, this study predicts a rich spectrum of resonant and virtual tetraquark candidates exhibiting heavy-quark spin symmetry multiplets, with specific guidance provided for their experimental detection through characteristic decay patterns and widths.
This review examines the fundamental principles of thermal field theory in a background magnetic field, focusing on equilibrium systems to analyze bulk thermodynamic properties and real-time observables relevant to the thermo-magnetic QCD plasma in heavy-ion collisions.
This paper defends Large-Momentum Effective Theory (LaMET) against recent claims that it suffers from an unquantifiable inverse problem, arguing that physics-guided systematic extrapolation remains the most reliable method for estimating uncertainties in parton distribution calculations even when lattice data precision is suboptimal.
This paper presents a theoretical study using unitarized chiral interactions to calculate and correlation functions, demonstrating that the inclusion of strong scattering effects—particularly the subthreshold resonance for and the mildly repulsive force for —successfully reproduces ALICE experimental data and validates femtoscopy as a powerful tool for probing strangeness-related hadronic interactions.
