We investigate the differential branching ratio, branching ratio,differential forward-backward asymmetry, the forward-backward asymmetry of thelepton pair and the lepton polarization asymmetry of the exclusive $B\to \tau^+\tau^- \gamma$ decay in the general two Higgs doublet model including theneutral Higgs boson effects. We analyse the dependencies of these quantities onthe model parameters and also on the neutral Higgs boson effects. We found thatthey get considerable enhancement from the two Higgs doublet model compared tothe standard model and neutral Higgs boson effects are quite sizable.Comment: 28 pages,15 figure
