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.

A Breath of Fresh Air for Molière: Detecting Molière Scattering using Jet Substructure Observables in Oxygen Collisions

This paper proposes that jet substructure observables, specifically the Soft Drop splitting angle and energy-energy correlators, in ultra-relativistic oxygen-oxygen collisions can uniquely detect rare, large-angle Molière scatterings between jet partons and quark-gluon plasma quasiparticles, offering a model-independent method to probe the medium's short-distance structure.

Equation of state and cumulants of proton multiplicity in equilibrium near critical point from Pade estimates

This paper proposes a method to constrain proton multiplicity cumulants in heavy-ion collisions by leveraging Pade-resummed lattice QCD data on the Lee-Yang singularity structure, revealing four distinct scenarios for critical point signatures that depend on the critical point's location and the slope of the chiral crossover curve.

Semi-inclusive deep-inelastic scattering on a polarized spin-1 target. II. Deuteron and spectator nucleon tagging

This paper develops a light-front theoretical framework for semi-inclusive deep-inelastic scattering on a polarized deuteron with spectator nucleon tagging, deriving tagged structure functions and spin asymmetries that highlight the role of the deuteron's D-wave component and provide essential tools for future experiments at Jefferson Lab and the Electron-Ion Collider.

The Effects of Multi-Λ\Lambda Hyperons on Collective Modes in Nuclei

This study employs self-consistent Hartree-Fock + Random Phase Approximation calculations to demonstrate that adding multiple Λ\Lambda hyperons to closed-shell nuclei systematically increases excitation energies and nuclear incompressibility, with the hyperons' dynamical influence remaining predominantly in phase with protons.
