Three Higgs doublet model with horizontal S 3 symmetry

Abstract

Abstract We present a brief overview of a three-Higgs-doublet Model CP-invariant with S 3-symmetry as a flavor symmetry. This model contains three Higgs SU(2) doublets as well as three right handed neutrinos, besides the usual Standard Model particles. We discuss some features of the Yukawa, Higgs and neutrino sectors of this model, and present some new results on the trilinear couplings of the Higgs sector, plus a fit of all parameters in the neutrino one.
