Abstract

We investigate the differential branching ratio, the branching ratio, differential forward-backward asymmetry, forward-backward asymmetry of the lepton pair, and lepton polarization asymmetry of the exclusive B-s-->tau(+)tau(-)gamma decay in the general two Higgs doublet model including the neutral Higgs boson effects. We analyze the dependences of these quantities on the model parameters and also on the neutral Higgs boson effects. We find that they get considerable enhancement from the two Higgs doublet model compared to the standard model, and the neutral Higgs boson effects are quite sizable.
