Chiral Symmetry and Finite Pion Mean Field in Nuclei

Abstract

We introduce the chiral symmetry in the description of finite nuclei with the hope to unify the hadron and nuclear physics. This trial becomes possible by introducing finite pion mean field, which contributes largely to enhance the spin-orbit splitting so as to provide the j-j magic number. We discuss the qualitative consequence of the finite pion mean field for various observables.
