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 Global View of the EDM Landscape

This paper utilizes the SFitter global analysis framework within an effective quantum field theory approach to interpret current permanent electric dipole moment (EDM) measurements via a hadronic-scale Lagrangian, revealing that while some parameters are well-constrained, others require more high-precision data and that theory uncertainties can be managed within the analysis.

Hybrid stars among mass gap objects are excluded by twin stars at 1.4M1.4\,M_\odot

This paper argues that hybrid stars are unlikely candidates for observed mass-gap compact objects because Bayesian analysis of modern mass-radius constraints favors equations of state with deconfinement occurring around 1.4M1.4\,M_\odot, which would produce twin stars that effectively rule out hybrid stars in the mass gap.

Projected Energy Correlators: Two-Loop Jet Functions and NNLL Resummation

This paper presents the next-to-next-to-leading logarithmic (NNLL) collinear resummation of projected NN-point energy correlators up to N=6N=6, incorporating newly computed two-loop jet functions and leading non-perturbative corrections, thereby establishing quantitative control over these observables for future precision αs\alpha_s extractions.

Chiral Quark Soliton Model And Nucleon Parton Distribution Functions

This paper elucidates how the Chiral Quark Soliton Model (CQSM), by uniquely incorporating non-local quark-quark correlations arising from spontaneous chiral symmetry breaking, successfully predicts various nucleon parton distribution functions, particularly the flavor asymmetry of sea-quark distributions, outperforming traditional effective meson theories like the Skyrme model.

D0D^0-Ds+D_s^+ Elliptic-Flow Splitting under Event-Shape Engineering: A Probe of Sequential Charm Hadronization

This study demonstrates that event-shape engineering in Pb-Pb collisions provides a sharper discrimination between sequential and simultaneous charm hadronization scenarios by revealing a geometry-dependent elliptic-flow splitting (Δv2\Delta v_2) and a species-specific response slope hierarchy that are unique to the sequential model.

Mechanical properties of the nucleon in the chiral confining model. I -- formal developments

This paper presents the formal developments for calculating the mechanical properties of the nucleon, including its mass, energy density, and pressure distribution, within a chiral confining model where massive constituent quarks interact with a pion cloud, utilizing the von Laue stability condition to determine trial states.

Mechanical properties of the nucleon in the chiral confining model. II -- in-medium evolution of the nucleon properties

This paper investigates the evolution of nucleon properties within nuclear matter using the chiral confining model, revealing how the interplay of confinement and chiral symmetry breaking drives mass modifications and repulsive three-body forces essential for nuclear saturation and neutron star equations of state.

Yoctosecond imaging of the ground state of 129^{129}Xe at the Large Hadron Collider

By combining Bayesian inference with hydrodynamic simulations and Large Hadron Collider data from Xe-Xe and Pb-Pb collisions, researchers successfully reconstructed the nearly maximally triaxial ground-state shape of the 129^{129}Xe nucleus, thereby establishing high-energy collider experiments as a quantitative tool for probing proton-neutron correlations driven by quantum chromodynamics.

Bottomonium Properties in QGP from a Lattice-QCD Informed T-Matrix Approach

This paper employs a thermodynamic T-matrix approach informed by recent lattice QCD data to analyze bottomonium dynamics in the quark-gluon plasma, revealing that while minor potential refinements suffice to describe correlation functions, stronger interference effects are required at larger quark-antiquark separations to accurately determine bound-state survival temperatures and spectral properties.
