Rare decay B Xsl+l- in a CP spontaneously broken two Higgs doublet model
Abstract
The Higgs boson mass spectrum and couplings of neutral Higgs bosons to fermions are worked out i n a CP spontaneously broken two Higgs doublet model in the large tanβ case. The differential branching ratio, forward-backward asymmetry, CP asymmetry and lepton polarization for B Xs l+ l- are computed. It is shown that effects of neutral Higgs bosons are quite significant when β is large. Especially, the CP violating normal polarization PN can be as large as several percents.
