B→sτ+τ−decay in the two Higgs doublet model with flavor changing neutral currents

Abstract

We study the decay width and forward-backward asymmetry of the lepton pair for the inclusive decay b --> s \tau^+ \tau^- in the two Higgs doublet model with three level flavor changing neutral currents (model III) and analyse the dependencies of these quantities on the model III parameters, including the leading order QCD corrections. We found that there is a considerable enhancement in the decay width and neutral Higgs effects are detectable for large values of the parameter \bar{\xi}_{N,\tau\tau}^D.
