Ground-state properties of finite nuclei in relativistic Hartree-Bogoliubov theory with an improved quark mass density-dependent model*

Year: 2025

Type: article

Abstract: A relativistic Hartree-Bogoliubov (RHB) model based on quark-meson coupling is developed with a new parametrization derived from experimental observables. Using this model, we systematically investigate the ground-state properties of even-even nuclei spanning , including binding energies, quadrupole deformations, root-mean-square charge radii, two-nucleon separation energies, two-nucleon shell gaps, and α -decay energies. Comparisons with available experimental data confirm that this subnucleon-based RHB model reliably describes the ground-state properties of finite nuclei.
