Nuclear structure in parity doublet model

Using an extended parity doublet model with the hidden local symmetry, we study some properties of nuclei in mean field approximation to see if could reproduce nuclear and also estimate value chiral invariant nucleon mass $$m_0$$ preferred by structure. We first determine our parameters using inputs from free space matter properties. Then, basic such as binding energy several different choices mass. observe that results approach experimental values is increased until $$m_0=700$$ MeV start deviate more experiments afterwards larger than MeV. From this observation, conclude then calculate selected compare them experiments. Finally, neutron-proton difference nuclei.
