Charge asymmetry in two-Higgs doublet models
arXiv:hep-ph/9812535 · doi:10.1016/S0370-2693(99)01400-8
Abstract
We discuss the features of a two-Higgs doublet model exhibiting a two stage phase transition. At finite temperatures electric charge violating stationary points are developed. In conjunction with {\em CP} violation in the Higgs or the Yukawa sector, the phase transition to the charge conserving vacuum, generates a net charge asymmetry , in the presence of heavy leptons, which may be well above the astrophysical bounds put on unless the heavy leptons are sufficiently massive. This type of transition may be of relevance for supersymmetric extensions of the Standard Model, since it shares the same features, namely two Higgs doublets and similar {\em CP} violating sources.
