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.

Probing Rotational Dynamics of Quark Gluon Plasma via Global Vorticity

This study introduces a data-driven approach to quantify global vorticity in relativistic heavy-ion collisions by analyzing transverse momentum spectra across various hadron species and collision conditions, revealing significant dependencies on particle type, centrality, and beam energy that offer new insights into the rotational dynamics and freeze-out properties of quark-gluon plasma.

Bayesian Analyses of Proton Multiple Flow Components in Intermediate Heavy Ion Collisions with Momentum-Dependent Interactions

Using a Bayesian framework with a Gaussian Process emulator to analyze Au+Au collision data at 1.23 GeV/nucleon, this study demonstrates that a momentum-dependent transport model constrained by proton flow observables favors a soft nuclear equation of state and mild in-medium suppression of baryon-baryon cross sections, while highlighting that momentum-independent models require significantly different parameters to reproduce the same data.

Quarkyonic matter and hadron-quark crossover from an ultracold atom perspective

This paper proposes a field-theoretical framework analogous to the BEC-BCS crossover in ultracold atoms to explain the hadron-quark crossover in dense matter, demonstrating that a tripling fluctuation effect can simultaneously account for the observed peak in the speed of sound and the baryon momentum-shell structure characteristic of quarkyonic matter.

Approximating the SS matrix for solving the Marchenko equation: the case of channels with different thresholds

This paper extends Marchenko inverse scattering theory to multi-channel systems with different thresholds by approximating the SS-matrix with a rational and sinc series expansion, demonstrating that closed-channel submatrices can be reconstructed from open-channel data and validating the method through both synthetic potential tests and the analysis of πN\pi N scattering data.

Inclusive hadroproduction of χc1(3872)χ_{c1}(3872), XbX_b and pentaquarks

This paper utilizes Born--Oppenheimer effective field theory factorization to provide genuine, fit-free predictions for the inclusive hadroproduction cross sections of the χc1(3872)\chi_{c1}(3872), its bottomonium partner, and various charmonium and bottomonium pentaquark states.
