$B\to X_sτ^+τ^-$ in a CP spontaneously broken two Higgs doublet model

Abstract

The differential branching ratio, CP asymmetry and lepton polarization $P_N$ for $B\to ^M X_sτ^+τ^-$ in a CP spotaneously broken two Higgs doublet model are compute d. ^M It is shown that contributions of neutral Higgs bosons to the decay are ^M quite significant when $\tanβ$ is large and $P_N$ can reach five persent.
