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.

Deciphering the dynamics of nuclear collisions with elongated structure of $^{20}$ Ne

This study investigates the impact of the intrinsic geometric structure and $\alpha$ -clustering of the $^{20}$ Ne nucleus on particle production in $^{20}$ Ne- $^{20}$ Ne collisions at 5.36 TeV, revealing that while these structural features significantly modify charged particle multiplicity, their effects on transverse momentum spectra and mean transverse momentum remain modest in central collisions within a non-hydrodynamic framework.

Analysis of elastic $α$ - $^{12}$ C scattering with machine learning in the cluster effective field theory

This paper demonstrates that cluster effective field theory, when combined with machine learning optimization techniques like Differential Evolution and Markov chain Monte Carlo, provides a reliable and systematic framework for accurately analyzing low-energy elastic $\alpha$ - $^{12}$ C scattering data relevant to stellar evolution and nucleosynthesis.

Proton mass decompositions in the NNLO QCD

This paper presents next-to-next-to-leading order (NNLO) QCD evaluations of proton and pion mass decompositions using gravitational form factors, comparing standard quark/gluon and trace-anomaly breakdowns with a novel twist-two/twist-four separation to demonstrate its advantages and reveal distinct parton-correlation behaviors between the two hadrons.

Gorkov algebraic diagrammatic construction for infinite nuclear matter

This paper introduces a novel many-body truncation for Gorkov self-consistent Green's function theory that combines first-order pairing correlations with third-order particle-number-conserving dynamical correlations to accurately predict the equation of state and spectral properties of infinite nuclear matter using modern chiral effective field theory Hamiltonians.

Scaled transverse-momentum spectra as a probe of collective dynamics in heavy-ion collisions

This paper demonstrates that a dimensionless, scaled transverse-momentum spectrum exhibits universal behavior across heavy-ion collision conditions, serving as a powerful new probe that reveals collective dynamics and provides independent constraints on quark-gluon plasma properties through Bayesian analysis.

Polarization-dependent mass modifications of $\phi$ meson with finite momentum in nuclear matter

This paper investigates the in-medium properties of the $\phi$ meson with finite momentum in nuclear matter, revealing that while transverse polarization mass shifts remain momentum-independent, longitudinal shifts decrease quadratically with momentum due to specific vector mean-field and derivative interactions, offering new predictions for upcoming experiments at J-PARC.

Finite size effects on critical correlations in momentum space

This paper presents a theoretical analysis demonstrating that finite size and lifetime effects in heavy-ion collisions modify the momentum-space two-point correlation function of baryon density, resulting in an effective scaling exponent that matches the infinite-system value only within a specific, experimentally accessible momentum range.
