Symmetry energy studies in the chiral soliton model

Abstract

We have studied the symmetry energy contribution to the binding energy per nucleon. The modifications of symmetry energy are performed in the framework of the in-medium modified chiral soliton model. The model incorporates the isospin symmetry breaking effects in the mesonic sector and reproduces the corresponding isospin breaking effects in the baryonic sector. Furthermore, the isospin breaking effects in the baryonic sector have been related to the nuclear symmetry energy.
