B → K *τ+τ− decay in the general two Higgs doublet model including the neutral Higgs boson effects

Abstract

We study the CP violating asymmetry, the forward–backward asymmetry of the lepton pair and the CP asymmetry in the forward–backward asymmetry for the exclusive decay B → K*τ+τ− in the general two Higgs doublet model including the neutral Higgs boson effects. We analyse the dependences of these quantities on the model III parameters. We found that the physical parameters studied above are of the order of 1%, and neutral Higgs boson effects are detectable for large values of the coupling ξ̄N,ττD.
