Abstract.

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 \(\tan\beta\) case. The differential branching ratio, forward-backward asymmetry, CP asymmetry and lepton polarization for \(B\rightarrow X_sl^+l^-\) are computed. It is shown that the effects of neutral Higgs bosons are quite significant when \(\tan\beta\) is large. Especially, the CP violating normal polarization \(P_{\mathrm {N}}\) can be as large as several percents.
