Rare decay [equation] in aCPspontaneously broken two-Higgs doublet model

摘要

The Higgs boson mass spectrum and couplings of the neutral Higgs bosons to the fermions are worked out in a CP spontaneously broken two-Higgs doublet model in the large ( aneta) case. The differential branching ratio, forward-backward asymmetry, CP asymmetry and lepton polarization for (B ightarrow X_sl^+l^-) are computed. It is shown that the effects of neutral Higgs bosons are quite significant when ( aneta) is large. Especially, the CP violating normal polarization (P_{mathrm {N}}) can be as large as several percents.
