Relativistic Density-Dependent Hartree Approach for Nuclear Matter in the Chiral-Symmetry-Breaking Model
-
Abstract
A relativistic density-dependent Hartree approach in the chiral-symmetry-breaking field model has been developed for nuclear matter. The coupling constants of the relativistic Hartree-Lagrangian are made density dependence and obtained from the relativistic Brueckner-Bethe-Goldstone results of nuclear matter. The calculated saturation nuclear density, binding-energy and compressibility for nuclear matter are close to the empirical ones.
