Isospin Symmetry Breaking Effects on the Properties of Asymmetrical Nuclear Matter and $\beta$-Stable Matter

Abstract

We have studied the influences of isospin symmetry breaking of nucleon-nucleon interaction on the various properties of asymmetrical nuclear matter and $\beta$-stable matter. For asymmetrical nuclear matter, it is found that by including this isospin symmetry breaking, the changes of bulk properties increase by increasing both density and asymmetry parameter. However, these effects on the total energy and equation of state of $\beta$-stable matter are ignorable. For asymmetrical nuclear matter, the validity of the empirical parabolic law in the isospin symmetry breaking case is shown. It is observed that the isospin symmetry breaking of nucleon-nucleon interaction affects the $\beta$-equilibrium conditions in $\beta$-stable matter.
