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 presents a next-to-leading order expansion formula for computing parton distribution functions from current-current correlators, which offer simple renormalization properties and avoid linear power divergences, alongside preliminary numerical results utilizing four-point functions on the lattice.
This paper establishes a fully general relativistic framework for analyzing non-radial polar oscillations in gravitationally coupled two-fluid neutron stars by deriving the necessary perturbation equations and boundary conditions, then numerically computing mode spectra to classify fundamental and pressure modes based on their fluid character.
This paper presents a unified four-body DWBA framework that derives a common Hamiltonian-based description for both pair-detected and single-particle inclusive breakup channels of three-body projectiles, successfully recovering established limits like IAV and CFH while providing new diagnostic tools for cluster approximations and target excitations.
This paper employs Landau singularity analysis within the Schwinger-Keldysh effective field theory framework to systematically identify frequency-space singularities induced by nonlinear interactions, thereby determining the power-law late-time relaxation modes of gapless fluctuations without explicitly performing loop integrations.
This paper presents a precise determination of the strong coupling constant through a global fit of heavy jet mass data, utilizing state-of-the-art theoretical predictions that combine fixed-order calculations, multiple resummation orders, and first-principles power corrections to demonstrate the critical role of resummation in achieving robust results and revealing evidence for negative power corrections in the trijet region.
This paper computes the exact kinematic contribution to diffractive deep inelastic scattering structure functions, demonstrating that previous high-energy approximations are insufficient and revealing an equally important soft quark contribution alongside the soft gluon term at high .
Using QCD sum rules with dimension-12 condensates, this study calculates the mass spectra of hexaquark states and finds that the ground states lie around 5.8 GeV, consistent with BESIII's non-observation of a near-threshold bound state, while also predicting masses for hidden-bottom candidates.
This contribution proposes and demonstrates that the utilization of cascade decay pathways via nuclear excitation by inelastic electron scattering (NEIES) and nuclear excitation by electron capture (NEEC) in storage rings and electron beam ion traps can significantly increase the production yield of the Th isomer, thereby facilitating its application in nuclear clocks and precision metrology.
This paper demonstrates that magnetic field-induced mixing between charged pions and longitudinally polarized rho mesons, amplified by rho wave-function renormalization suppression, provides a robust mechanism explaining the non-monotonic behavior of charged pion masses observed in lattice QCD.
This paper utilizes a Dyson-Schwinger and Bethe-Salpeter approach to demonstrate that the transition from chiral symmetry breaking to restoration in light meson spectra is governed by the location of quark propagator poles relative to the integration domain, offering new insights into the potential emergence of chiral spin symmetry in QCD.
