t→cH0 decay in the general two Higgs doublet model

We study the flavor changing t→cH⁰ decay in the framework of the general two Higgs doublet model, the so called model III. Here, we take the Yukawa couplings complex and switch on the CP violating effects. We predict the branching ratio six orders larger compared to the one calculated in the SM, namely, B Rtilde 10^-7, and observe a measurable CP asymmetry, at the order of ∼10^-2.
