We study the charged t® b W h0 and t® b W 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®
b W h0) ~ 10-6
and BR (t® b W A0) ~ 10-8. Furthermore, we find a CP asymmetry, of the order of 10-2, for both decays.
