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 study extends the alpha-particle non-locality effect within the two-potential approach and employs machine learning models, particularly decision tree regression and XGBRegressor, to significantly improve the accuracy of alpha-decay half-life predictions for known and superheavy nuclei compared to traditional benchmarks.
This paper presents a three-dimensional analysis of the two-pion source in Au+Au collisions at 200 GeV using Monte-Carlo simulations and compares these results with recent centrality-dependent measurements from the PHENIX Collaboration to refine the description of pion emission shapes using Levy-stable distributions.
This paper applies radiative corrections to recent MINERvA antineutrino-hydrogen scattering data to extract the nucleon axial-vector form factor and radius, thereby enabling more precise comparisons with lattice QCD predictions and reducing uncertainties in neutrino interaction modeling.
By combining thermal field theory and statistical mechanics, this paper reexamines the relativistic Barnett effect in a rigidly rotating free Fermi gas, demonstrating that spin-rotation coupling induces spin polarization and a magnetic susceptibility proportional to the moment of inertia, which exhibits Curie-like behavior in the high-temperature limit.
This paper investigates the structural impact of superconductivity and internal magnetic fields on hybrid stars by proposing a new anisotropic model that combines color superconducting quark matter with hadronic matter, ultimately exploring how the resulting pressure anisotropy influences stellar mass and generates continuous gravitational waves.
Using continuum Schwinger function methods, this paper challenges the simple hydrogen-like atomic model of ground-state scalar and pseudoscalar charmonia by revealing their complex internal structures, including nontrivial orbital angular momentum contributions and non-positive-definite distribution amplitudes, while providing theoretical benchmarks for understanding heavy-quark hadrons.
This paper presents the first real-time tensor-network simulation of hadronic scattering in a (1+1)-dimensional SU(2) lattice gauge theory, revealing that while meson-meson and baryon-baryon collisions exhibit predominantly elastic dynamics similar to the Schwinger model, meson-baryon interactions display unique entanglement-driven behavior characterized by the spatial delocalization of slower wavepackets.
The STAR experiment at RHIC presents the first measurement of inclusive polarization in Ru+Ru and Zr+Zr collisions at GeV, finding that the polarization parameters are consistent with zero across various transverse momenta and collision centralities, aligning with previous measurements and transport-model calculations.
This paper demonstrates that macroscopic observables can obey arbitrary linear evolution equations, including those appearing acausal, by constructing a causal and covariantly stable kinetic model where the dispersion relation is encoded entirely in the initialization of microscopic degrees of freedom, thereby challenging the notion that microscopic causality alone constrains the analytic form of dispersion relations at real wavenumbers.
This paper evaluates pion-induced QED radiative corrections to the inverse beta decay cross section using heavy baryon chiral perturbation theory, demonstrating that these effects are small enough to enable sub-permille theoretical precision for antineutrino energies above 10 MeV.
