Temperature and Density Effects on the Nucleon Mass Splitting

High Energy Physics - Phenomenology 2016-08-15 v1 Nuclear Theory

Abstract

The finite temperature and finite density dependence of the neutron-proton mass difference is analysed in a purely hadronic framework where the ρω\rho-\omega mixing is crucial for this isospin symmetry breakdown. The problem is handled within Thermo Field Dynamics. The present results, consistent with partial chiral and charge symmetry restoration, improve the experimental data fit for the energy difference between mirror nuclei.
