Description

We calculate the splitting between fermion and antifermion effective masses in high temperature gauge theories in the presence of a nonvanishing chemical potential due to the CP-asymmetric fermionic background. In particular we consider the case of left-handed leptons in the SU(2)direct-product U(1) theory when the temperature is above 250 GeV and the gauge symmetry is restored
