CP Violation in a Multi-Higgs Doublet Model

Abstract

We study CP violation in a multi-Higgs doublet model based on a $S_3\times Z_3$ horizontal symmetry. We consider two mechanisms for CP violation in this model: a) CP violation due to complex Yukawa couplings; and b) CP violation due to scalar-pseudoscalar mixings. We find that the predictions for ${\epsilon }^{\prime }/\epsilon$, CP violation in B decays and the electric dipole moments of neutron and electron are different between these two mechanisms. These predictions are also dramatically different from the minimal Standard Model predictions.
