Abstract

We study the charged t → bW h0 and t → bW A0 decays in the framework of the general two Higgs doublet model, so called model III and beyond. Here, we take the Yukawa couplings complex and introduce a new complex parameter due to the physics beyond the model III, to switch on the CP violating effects. We predict the branching ratios as BR(t → bW h0 ) ∼ 10−6 and BR(t → bW A0 ) ∼ 10−8 . Furthermore, we find a CP asymmetry, of the order of 10−2 , for both decays.

Keywords

t → bWh0 and t → bWA0 decays; general two Higgs doublet model (III); CP violating effects; branching ratios
