Özet

We study the decay width and CP asymmetry of the inclusive process b --> sgg (g denotes gluon) in the three and two Higgs doublet models with complex Yukawa couplings. We analyze the dependencies of the differential decay width and CP asymmetry to the s-quark energy E-s and CP violating parameter theta. We observe that there exist a considerable enhancement in the decay width and CP asymmetry is at the order of 10(-2). Further, it is possible to predict the sign of C-7(eff) using the CP asymmetry.
