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.

Asymptotic Freedom and Vacuum Polarization Determine the Astrophysical End State of Relativistic Gravitational Collapse: Quark--Gluon Plasma Star Instead of Black Hole

The paper proposes a theoretical model where relativistic gravitational collapse results in a hypermassive quark–gluon plasma (QGP) star rather than a black hole, stabilized against implosion by the combined effects of nonlinear electrodynamics (vacuum polarization) and QCD asymptotic freedom.

First Extraction of the Matter Radius of 132^{132}Sn via Proton Elastic Scattering at 200 MeV/Nucleon

By measuring proton elastic scattering at approximately 200 MeV/nucleon, researchers extracted the first matter radius for 132^{132}Sn (4.7580.024+0.0234.758^{+0.023}_{-0.024} fm), finding that current theoretical models cannot simultaneously reconcile this value with the known charge radius.

Non-Hermitian Renormalization Group from a Few-Body Perspective

This paper establishes a rigorous microscopic foundation for non-Hermitian renormalization group (RG) methods by deriving them from the invariance of scattering amplitudes in few-body systems, providing a unified framework that links quantum measurement effects to phenomena in both high-energy and atomic physics, such as nuclear scale anomalies and halo nuclei structures.
