Tree-Level Vacuum Stability in Multi Higgs Models

High Energy Physics - Phenomenology 2007-05-23 v1

Abstract

In the most general model with two Higgs doublets, if a minimum that preserves the U(1)emU(1)_{em} symmetry exists, then charge breaking (CB) minima cannot occur. The depth of the potential at a stationary point that breaks CB or CP, relative to the U(1)emU(1)_{em} preserving minimum, is proportional to the squared mass of the charged or pseudoscalar Higgs, respectively.
