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.

Nuclear Deformation Effects on Charmonium Suppression in Au+Au and U+U Collisions

This study demonstrates that while intrinsic nuclear deformation in U+U collisions has a negligible effect on the overall charmonium yield suppression compared to Au+Au collisions, it significantly influences charmonium momentum anisotropy and distinguishes between tip-tip and body-body collision configurations, with these effects being more pronounced for excited states due to their lower binding energies.

Prolate-oblate shape competition and impact on charge radii in Bk isotopes

Using the deformed relativistic Hartree-Bogoliubov theory, this study reveals that in well-deformed odd-AA Bk isotopes, oblate shapes yield larger charge radii than prolate ones due to a central proton density depression caused by the non-occupation of the 3s1/23s_{1/2} orbital, thereby establishing a microscopic link between nuclear shape, single-particle occupancy, and nuclear size.

Constraining the neutron skin of 208^{208}Pb with anisotropic flow in Pb+Pb collisions at the LHC

This study utilizes an improved multi-phase transport model to analyze Pb+Pb collisions at the LHC, finding that while anisotropic flow measurements can exclude large neutron skins in 208^{208}Pb, they exhibit a geometric degeneracy that limits their ability to precisely distinguish between zero and moderate neutron skin values.

Bayesian neural network with autoencoder for model-based description of αα-particle preformation factor

This study introduces a hybrid Bayesian neural network with an autoencoder framework integrated with the cosh potential to significantly improve the prediction accuracy and uncertainty quantification of the α\alpha-particle preformation factor, successfully revealing nuclear shell effects and validating the stability of the predicted superheavy island near N=184N=184.

Correlation between nuclear isospin asymmetry and αα-particle preformation probability for superheavy nuclei from a Bayesian inference

This study employs a Bayesian inference framework combined with Markov Chain Monte Carlo sampling to develop a phenomenological model that reveals a significant suppressing effect of nuclear isospin asymmetry on α\alpha-particle preformation probability in superheavy nuclei, thereby providing a high-precision theoretical tool for predicting α\alpha decay half-lives and guiding future experimental exploration.

Physics-Informed Global Extraction of the Universal Small-xx Dipole Amplitude

This paper presents a physics-informed neural network approach to extract a universal small-xx dipole scattering amplitude directly from global DIS and photoproduction data without rigid parametric assumptions, successfully resolving the long-standing tension between total and charm cross-section channels while providing a smooth, non-negative input for Color Glass Condensate phenomenology.
