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 utilizes state-of-the-art lattice calculations and experimental form factor data to visualize momentum flow and color-Lorentz forces within the nucleon, revealing that the gluon anomaly generates a critical attractive force on quarks comparable in strength to heavy-quark confinement.
This paper investigates the impact of strongly-interacting dark matter, modeled by a first-principles QCD-like gauge theory, on neutron star structure and confirms that such dark matter can be accommodated within current observational constraints.
This paper challenges the interpretation of the nucleon's momentum current density as a continuous medium's pressure and shear forces, arguing instead that color interactions are long-ranged and that only the isotropic vacuum pressure term derived from the QCD trace anomaly effectively provides the confining potential for quarks.
This paper utilizes a hybrid theoretical model combining equivalent photon approximations, GiBUU pre-equilibrium dynamics, and statistical decay frameworks to analyze new ALICE ultraperipheral collision data, successfully explaining proton and neutron emission patterns in photon-induced nuclear processes, particularly the near-maximal cross-section for single-proton emission and the high-energy tail of neutron distributions.
This paper demonstrates that including twist-four kinematic power corrections modifies the subtracted constants in deeply virtual Compton scattering dispersion relations, causing the helicity-conserving amplitude to depend on double distributions in addition to the -term, a mixing effect that significantly impacts the extraction of pressure forces from Jefferson Lab data.
This paper demonstrates that kinematic power corrections in deeply virtual Compton scattering dispersion relations provide a novel experimental constraint on nucleon momentum, pressure, and total angular momentum distributions, with continuum and lattice-QCD predictions indicating that momentum distributions account for approximately one-third of the signal at .
This paper investigates the spatial distributions of energy density, pressure, and shear forces within a two-flavor Skyrme model including vector mesons, revealing that the energy-momentum tensor's pseudo-gauge dependence—arising from nonvanishing surface terms of spin currents—causes significant differences between canonical and Belinfante forms, including singularities in the canonical pressure and shear-force distributions at the nucleon center.
This paper introduces a new parton-shower algorithm that exactly reproduces the dynamics of linearized effective kinetic theory to provide a first-principles description of jet thermalization in QCD plasmas, overcoming previous limitations by properly incorporating recoils, holes, quantum statistics, and merging processes.
This paper presents the first next-to-leading-logarithmic QCD analysis of electromagnetic corrections to the semileptonic weak Hamiltonian, calculating mixed corrections to the vector coupling to yield a refined radiative correction value that enhances the consistency of first-row CKM unitarity tests.
This paper presents a systematic study of fission barriers and static properties for even-even actinides from Th to Cf using the Warsaw macroscopic-microscopic model with a high-resolution Fourier-over-Spheroid parameterization, revealing good agreement with empirical data and identifying a distinct third hyperdeformed minimum in Thorium isotopes that is absent in heavier actinides.
