Description

Models beyond the standard model with extra scalars have been highly motived by the discobery ofthe Higgs boson. The two Higgs doublet model type III considers the most general case for the scalarpotential, allowing mixing between neutral CP-even and CP-odd scalars fields. This work presentsthe results of the study on the t -> c gamma, t -> c Z, and t -> c h_1 decays, where h_1 is the StandardModel Higgs boson. The neutral flavor changing is generated by top-charm-Higgs coupling givenby the Yukawa matrix.
