CP Violation in the scalar sector

High Energy Physics - Phenomenology 2016-04-05 v1

Abstract

Models with an extended scalar sector may in principle provide new sources of CP violation originating in the scalar potential. One of the simplest ways to implement this idea is to have CP violation in a two-Higgs-doublet model. Here, it leads to CP violation in trilinear weak gauge boson couplings. We discuss how these couplings are becoming constrained in the alignment limit. In a model with three Higgs doublets, subject to an S3S_3 symmetry, several complex vacua are possible. Some of these, but not all, may lead to spontaneous CP violation.
