On introducing Charge-Symmetry-Breaking terms to nuclear Energy Density Functionals

Abstract

The Charge-Symmetry-Breaking (CSB) character of the nucleon-nucleon interaction is well established. This work presents two different ways of introducing such effects into a nuclear Energy Density Functional (EDF). CSB terms are either coming from the effective theory expansion or are derived from electromagnetic mixing of ${\rho }^0$ and $\omega$ mesons. These terms are then introduced to Skyrme and Quark-Meson-Coupling EDFs, respectively.
