ABSTRACT

Conditions for spontaneous Charge-Parity (CP) violation in the scalar potential sector of general S(3) Higgs-doublet model (3HDM) are analyzed. An analysis of the Higgs sector of the minimal S(3)-invariant extension of the Standard Model including CP violation arising from the spontaneous breaking of the electroweak symmetry is presented. This extended Higgs sector with three SU(2) doublets Higgs fields with complex vev’s provides an interesting scenario to analyze the Higgs masses spectrum, trilinear self-couplings and CP violation. We present how the spontaneous electroweak symmetry breaking, coming from three S(3) Higgs fields, gives an interesting scenario with nine physical Higgs and three Goldstone bosons, when spontaneous CP violation arises from the Higgs field S(3) singlet Hs.
