One-Loop Charge-Breaking Minima in the Two-Higgs Doublet Model

High Energy Physics - Phenomenology 2020-05-20 v1

Abstract

We analyze the vacuum structure of the one-loop effective potential in the two Higgs doublet model. We find that electroweak-breaking vacuua can coexist with charge breaking ones, contradicting a theorem valid at tree-level. We perform a numerical analysis of the model and supply explicit parameter values for which charge-breaking vacuua can be the global minimum of the theory, and deeper than charge-preserving ones.
