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 l epton polarization for the exclusive decay B --> K *l(+)l(-) in the two Hig gs doublet model with three level flavor changing neutral currents (model I II) and analyse the dependencies of these quantities on the the selected pa rameters, xi(U,D), of model III including the next to leading QCD correctio ns. It is found that to look for charged Higgs effects, the measurements of the branching ratio, forward-backward asymmetry and the longitudinal lepto n polarization for the decay B --> K * l(+)l(-) are promising.
