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.

ψ(2S)\psi(2S) production in jets using NRQCD

This paper utilizes recent LHCb data to demonstrate that both the Fragmenting Jet Function (FJF) and Gluon Fragmentation Improved Pythia (GFIP) formalisms significantly outperform default Pythia+NRQCD predictions in describing ψ(2S)\psi(2S) production in jets, while highlighting the distribution's utility as a discriminator to reveal large discrepancies among different ψ(2S)\psi(2S) Long-Distance Matrix Element (LDME) extractions.

Toward a Unified Understanding of the Dense Matter Equation of State

This paper reviews recent advancements in constraining the dense matter equation of state by synthesizing heavy-ion collision and multi-messenger astrophysics data through three key frameworks—NMMA, MUSES, and BAND—and outlines a path toward integrating these methods into a unified workflow for precision nuclear physics.

Dynamically Generated Fermi Surface Mismatch and Relativistic Superfluidity in a Two-Component Massless Fermionic Theory

This paper demonstrates that in a massless two-component Dirac theory with exact SU(2) flavor symmetry, the condensation of a self-interacting vector boson dynamically generates a Fermi surface mismatch through spontaneous symmetry breaking, thereby enabling the formation of a stable relativistic superfluid and extending the Chandrasekhar-Clogston limit into a surface within coupling space.

Investigating forward-backward asymmetry in D-meson production and anisotropic flow in p-Pb collisions at the LHC

Using the heavy-flavor improved AMPT model, this study demonstrates that the forward-backward asymmetry in prompt D0 meson production and elliptic flow in 8.16 TeV p-Pb collisions arises from the interplay of initial-state cold nuclear matter effects and final-state partonic interactions, providing evidence for the formation of a partonic medium in high-multiplicity events.
