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.

Effects of flavor-mixings on charged kaon and pion parton distribution functions

This paper investigates the impact of a novel flavor-mixing interaction arising from vacuum polarization on the parton distribution functions of charged kaons and pions within the U(3) Nambu--Jona-Lasinio model, demonstrating that these mixing effects, which are proportional to quark effective mass differences, significantly improve the agreement of theoretical predictions with experimental data at specific momentum fractions.

Microscopic Spin-Parity Distributions of Fission Fragments

This study presents the first microscopic characterization of fission fragment spin-parity distributions using time-dependent Hartree-Fock-Bogoliubov calculations, revealing that dynamical pair breaking significantly populates unnatural-parity states and creates parity patterns dependent on fragment mass parity, thereby challenging the equiprobable assumptions of current statistical de-excitation models.

Light clusters in warm magnetized stellar matter: equation of state and thermodynamic response

This study investigates the interplay between light nuclear cluster formation and strong magnetic fields in warm, beta-equilibrated stellar matter using a generalized relativistic mean-field framework, revealing how their combined effects significantly modify the equation of state's thermodynamic stiffness and heat-storage properties to provide crucial insights for modeling proto-neutron stars and merger remnants.

Two-neutrino double-weak decays of 126^{126}Xe and 134^{134}Xe from different many-body methods

This study calculates the nuclear matrix elements and half-lives for the two-neutrino double-electron capture of 126^{126}Xe and double-beta decay of 134^{134}Xe using four different many-body methods, finding consistent predictions that suggest 134^{134}Xe's half-life may be within reach of next-generation experiments while 126^{126}Xe's is approximately an order of magnitude longer.

Line Tension Reshapes Nucleation at Surface Edges: A Generalized Theory for Nanopore Activation

This paper presents a generalized nucleation theory that incorporates edge-induced line tension to derive a closed-form expression for nanopore activation, revealing how geometric confinement and interfacial asymmetry significantly reshape nucleation energy landscapes and offer new strategies for controlling phase transitions in nanoscale environments.
