B→K*l+l- decay in the two Higgs doublet model with flavor changing neutral currents

We study the decay width, forward-backward asymmetry and the longitudinal lepton polarization for the exclusive decay B --> K *l(+)l(-) in the two Higgs doublet model with three level flavor changing neutral currents (model III) and analyse the dependencies of these quantities on the the selected parameters, xi(U,D), of model III including the next to leading QCD corrections. It is found that to look for charged Higgs effects, the measurements of the branching ratio, forward-backward asymmetry and the longitudinal lepton polarization for the decay B --> K * l(+)l(-) are promising.
