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.

Spectroscopic factors as a probe of nuclear shape in 44^{44}S via one-neutron knockout reaction

This study utilizes antisymmetrized molecular dynamics combined with the generator coordinate method to demonstrate that spectroscopic factors and reaction cross sections from one-neutron knockout reactions on 44^{44}S serve as sensitive probes for investigating shape mixing and fluctuations in this neutron-rich nucleus.

Universal scaling of transport coefficients near the liquid-gas critical point

This paper employs a novel real-time functional renormalization group formulation to compute universal scaling functions for thermal diffusivity and shear viscosity near the liquid-gas critical point, revealing a mild dependence on the thermodynamic path that contrasts with the Kawasaki approximation and demonstrating good agreement with experimental data.

Asymptotics of superfluid Bjorken flow

This paper investigates the late-time asymptotic behavior of superfluid Bjorken flow using Mueller-Israel-Stewart theory coupled to a complex scalar field, revealing that dissipative evolution leads to novel transseries solutions containing τalnτ\tau^{-a\ln \tau} factors that encode initial data dilution and exhibit either damped fall-off or oscillations depending on the condensate relaxation rate, with potential implications for heavy-ion collision experiments.

Symmetry Energy from Two-Nucleon Separation Energies of Pb and Ca Isotopes

This study utilizes the deformed relativistic Hartree-Bogoliubov theory and experimental mass data to derive the symmetry energy coefficients for Pb and Ca isotopes from two-nucleon separation energies, ultimately determining a model-independent volume symmetry energy of approximately 27.0 MeV by constraining the surface-to-volume energy ratio.

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

This study investigates the impact of the intrinsic geometric structure and α\alpha-clustering of the 20^{20}Ne nucleus on particle production in 20^{20}Ne-20^{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.

Chiral-scale effective field theory for dense and thermal systems

This paper establishes a new chiral-scale density counting (CSDC) power counting scheme for chiral-scale effective field theory, demonstrating its ability to accurately describe nuclear matter properties near saturation density and the liquid-gas phase transition critical temperature while highlighting the crucial role of quantum corrections in dense and thermal systems.
