Neutral Higgs effects on rare decay B→Xsl+l- in the T2HDM

We calculate the new physics contributions to the branching ratios of the rare decays B→Xsl+l- (l=e,μ) induced by neutral Higgs bosons loop diagrams in the top quark two-Higgs-doublet model (T2HDM). From the numerical calculations, we find that (a) the neutral Higgs boson's correction to B→Xsl+l- decays interferes constructively with its standard model counterpart, but small in magnitude; (b) the neutral Higgs contributions to the branching ratio of B→Xsl+l- decay can be neglected safely if their masses are larger than 100GeV and tanβ≤40.
