Breaking of Charge Independence of Nucleon-Nucleon Interaction and Bulk Properties of Nuclear Matter

Abstract

The effects of charge independence breaking of nucleon-nucleon interaction on the bulk properties of nuclear matter are investigated. Our results indicate that at high densities, the inclusion of charge dependence in the nucleon-nucleon potential affects the bulk properties of nuclear matter. However, at low densities, this effect is not considerable. It is seen that the change of our results for the nuclear matter calculations due to the breaking of the charge independence increases by increasing density. It is shown that the energy contribution of the ${}^1{S}_0$ channel is sensitive to considering the charge dependence in the nucleon-nucleon interaction. It is indicated that the effects of charge independence breaking on the calculated equation of state of nuclear matter are ignorable.
