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.

From the universal Lindblad equation to Boltzmann equations: in-QGP quarkonium dynamics

This paper establishes a systematic theoretical foundation for quarkonium dynamics in the quark-gluon plasma by deriving coupled singlet-octet Boltzmann transport equations directly from universal Lindblad equations within pNRQCD, thereby extending semiclassical descriptions beyond the small-dipole approximation and identifying additional collision terms absent in previous rotating-wave approximations.

Density-induced dark-baryon conversion in $\Delta-$ admixed hypernuclear neutron stars

This study demonstrates that in neutron stars containing hyperons and $\Delta$ resonances, density-induced conversion of neutrons into neutral dark baryons is self-consistently determined by chemical equilibrium rather than Higgs exchange, leading to suppressed dark-baryon abundances and equation-of-state modifications that constrain lighter dark-baryon masses against observed massive pulsar data.

Generative artificial intelligence for reconstructing neutron-star matter

This paper introduces a generative AI framework using denoising diffusion models to reconstruct the neutron-star equation of state by learning an inspectable prior from nuclear theory while exactly enforcing physical constraints, thereby resolving the ill-posed inverse problem of inferring matter properties from sparse observational data without biasing the results.

Bound-state spectra of $\chi_{cJ}$ in finite nuclei and the universal pattern of mass levels

This study predicts the existence of $\chi_{cJ}$ -nuclear bound states across various nuclei using in-medium mass shifts from virtual $D^{(*)}\bar{D}^{(*)}$ loops, revealing a universal level-spacing pattern that decreases with nuclear mass and could be verified in future experiments at the upgraded JLab facility.

Revised $^{45}$ V( $p,\gamma$ ) $^{46}$ Cr reaction rate and its impact on the production of $^{44}$ Ti in core-collapse supernovae

By incorporating a more precise mass measurement of $^{46}$ Cr and new spectroscopic factors to revise the $^{45}$ V( $p,\gamma$ ) $^{46}$ Cr reaction rate, this study demonstrates that the resulting 69% increase in the rate significantly boosts $^{44}$ Ti yields in proton-rich core-collapse supernova ejecta, thereby reconciling previous conflicting sensitivity analyses.

Data-Driven Statistical Ensembles of Chiral Nuclear Interactions

This paper employs normalizing flows to construct statistical ensembles of chiral nuclear interactions, revealing non-Gaussian correlations among low-energy constants and establishing a framework for systematically constraining nuclear forces with experimental and astrophysical data.

Symbolic Regression for Interpretable Emulation of Proton Collective Flow in Intermediate-Energy Heavy-Ion Collisions

This paper demonstrates that symbolic regression can effectively emulate the isospin-dependent Boltzmann-Uehling-Uhlenbeck transport model to predict proton collective flow observables with accuracy comparable to deep neural networks while providing interpretable analytic expressions and faster evaluation, despite requiring longer training times.

The elliptic wind on jet wakes in high-energy heavy-ion collisions

This paper proposes and calculates how the elliptic anisotropy of the quark-gluon plasma's density gradient and flow in non-central heavy-ion collisions distorts jet-induced medium responses into an azimuthally dependent elliptic wind, offering a new observable in $\gamma$ -jet events to constrain the QGP's shear viscosity.

Three-qubit entanglement in the Bethe-Heitler process

This paper proposes utilizing the Bethe-Heitler process ( $e+p\to e+p+\gamma$ ) as a laboratory to generate and validate high-fidelity bipartite and genuine tripartite entanglement, specifically identifying thousands of GHZ and W states below 5 GeV center-of-mass energy through event simulations.

Confining density functional approach to the QCD phase diagram at low temperatures and thermal twin stars

This paper presents a confining density functional equation of state for hybrid stars that reveals the existence of "thermal twin stars" at finite temperatures, suggesting that the presence of such disconnected branches serves as a new criterion to exclude strong color superconductivity and assess the explodability of core-collapse supernovae.
