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 high-precision measurements of quarkonia and vector meson production in peripheral and ultraperipheral heavy-ion collisions at LHCb, compares them with theoretical models, and discusses future prospects for the upgraded detector in Run 3.
This paper proposes a new classification for scalar mesons and identifies as a primary glueball candidate, utilizing a topological soliton framework to model glueball energy spectra and internal structures in agreement with lattice QCD and experimental data.
This chapter provides an introduction to nuclear many-body theory and reaction mechanisms to explain how low-energy neutrinos interact with nuclear matter and how these interactions influence astrophysical processes.
This contribution develops a phenomenological approach that refines the elastic scattering cross sections for - interactions in free space by decomposing the scattering amplitude into a 2N interaction component and a residual component fitted with energy-dependent Legendre polynomials, thereby establishing a crucial foundation for future studies of three-nucleon forces in nuclei via the ($p,pd$) reaction.
This paper proposes a new measurement technique that combines jet charge with global event shapes (specifically 1-jettiness in DIS) to simultaneously probe quark flavor dynamics in both initial-state nucleon structure and final-state hadronization processes.
By performing general-relativistic simulations, the authors demonstrate that the "favoured" branch of twin stars in a mass-radius sequence is determined by which configuration can withstand larger perturbations before migrating to the other branch, a property that can be predicted using binding energies rather than full simulations.
This study investigates how the increase in symmetry energy and chaotic magnetic fields influence the structural properties and gravitational wave observables of neutron stars, and demonstrates that magnetic fields significantly soften the equation of state for low-mass stars and markedly reduce their tidal deformability.
The paper proposes that steep matter-density gradients in neutron star interiors can produce neutrino-antineutrino pairs through a mechanism analogous to the Schwinger effect, potentially offering a new way to probe neutron star structure and dense QCD.
This paper provides a unified theoretical framework for the angular structure of energy-energy correlators (EECs) in heavy-ion collisions, demonstrating how they transition from being dominated by collective hydrodynamic flow at large angles to being controlled by hydrodynamic modes and light-ray operator product expansions at smaller angles.
This paper presents a global analysis of HERA data using a next-to-leading order (NLO+NLL) Balitsky-Kovchegov framework to extract the non-perturbative initial conditions for the Color Glass Condensate, utilizing a Bayesian approach to provide a streamlined method for estimating theoretical uncertainties.
