Fermion and Anti-Fermion Effective Masses in High Temperature Gauge Theories in $C P$ -Asymmetric Background

A. Erdas · C. W. Kim · J. A. Lee

Abstract

We calculate the splitting between fermion and anti-fermion effective masses in high temperature gauge theories in the presence of a non-vanishing chemical potential due to the $C P$ -asymmetric fermionic background. In particular we consider the case of left-handed leptons in the $S U (2) \otimes U (1)$ theory when the temperature is above $250$ GeV and the gauge symmetry is restored.
