B Xsτ+τ- in a CP softly broken two Higgs doublet model
Abstract
The differential branching ratio, forward-backward asymmetry, CP asymmetry and lepton polarization for a B-meson to decay to strange hadronic final states and a τ+τ- pair in a CP softly broken two Higgs doublet model are computed. It is shown that contributions of neutral Higgs bosons to the decay are quite significant when β is large. And it is proposed to measure the direct CP asymmetry in back-forward asymmetry.
