b --> s g g decay in the two and three Higgs doublet models with CP violating effects

Abstract
We study the decay width and CP-asymmetry of the inclusive process b--> s g g (g denotes gluon) in the three and two Higgs doublet models with complex Yukawa couplings. We analyse the dependencies of the differential decay width and CP-asymmetry to the s- quark energy Es and CP violating parameter θ. 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 C7eff using the CP asymmetry.
