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.
This paper presents a combined thermal and coalescence model for heavy-ion collisions in the few-GeV regime that successfully reproduces proton, pion, and deuteron yields but underpredicts the production of H and He nuclei by a factor of two compared to experimental data.
This paper investigates the application range of perfect spin hydrodynamics in both classical and quantum frameworks by analyzing the relationships between spin polarization, particle mass, temperature, and hydrodynamic flow, providing insights crucial for modeling heavy-ion collisions.
This paper reviews recent advancements in spin hydrodynamics, detailing the theoretical framework of perfect spin hydrodynamics through two equivalent approaches, establishing its applicability to late-stage heavy-ion collisions, and discussing near-equilibrium dynamics.
This paper presents lattice QCD calculations of the odd Mellin moments of the pion valence-quark generalized parton distribution up to fifth order across a range of skewness values, utilizing boosted pion states and advanced renormalization techniques to extract skewness-dependent moments through polynomiality-constrained fits.
This paper presents an exact analytical evaluation of the two-photon exchange correction to elastic lepton-proton scattering at low energies using heavy-baryon chiral perturbation theory up to NNLO, revealing non-vanishing proton structure effects and demonstrating good perturbative convergence for the kinematic regime relevant to the MUSE experiment.
This paper proposes and validates an efficient nucleon-pair truncation scheme for the configuration-interaction shell model, which combines variationally optimized pair condensates with angular momentum projection to accurately describe low-lying states and shape coexistence in medium-heavy nuclei where full calculations are computationally prohibitive.
This paper presents a systematic shell model study of the isotonic chain (–77) using a newly developed effective interaction derived via principal component analysis, which successfully reproduces experimental nuclear properties and provides predictions for proton-rich nuclei beyond current experimental reach.
This study investigates the structure and enhanced stability of the isomer in the proton drip-line nucleus Os using configuration-constrained potential-energy-surface calculations, revealing that uncertainties in spin-orbit coupling strength can significantly alter the isomer's orbital composition and deformation while suggesting a potential stability inversion between high- isomers and ground states in this mass region.
Using the Jacobi-coordinate No-Core Shell Model with chiral interactions, this study demonstrates that including two-nucleon charge density operators is essential for accurately predicting the charge form factors and radii of light isoscalar nuclei like Li and Be, thereby resolving the long-standing issue of charge radius underestimation in *ab initio* calculations.
