$B\to X_s{\tau }^{+}{\tau }^{-}$ in a CP spontaneously broken two Higgs doublet model

Abstract

The differential branching ratio, CP asymmetry and lepton polarization $P_N$ for $B{\to }^M{X}_s{\tau }^{+}{\tau }^{-}$ 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 $\tan \beta$ is large and $P_N$ can reach five persent.
