b -> s γdecay in the two Higgs doublet model with flavor changing neutral currents

Abstract

We study the b --> sγdecay including the next to leading QCD corrections in the two Higgs doublet model with flavor changing neutral currents at the tree level. We find the constraints to the flavor changing parameters of the model, using the experimental results on the branching ratio of B --> X_s γdecay, provided by the CLEO Collaboration, the restrictions coming from the ΔF=2 (F=K,D,B) mixing and the ρparameter.
