Phys. Rev. D 59, 011701(R) (1998) [4 pages]Promising process to distinguish supersymmetric models with large tan β from the standard model: B⃗Xsμ+μ-
It is shown that in supersymmetric models the large supersymmetric contributions to B⃗Xsμ+μ- come from the Feynman diagrams which consist of exchanging neutral Higgs boson loops and are proportional to mbmμtan3β/mh2 when tan β is large and the mass of the lightest neutral Higgs boson mh is not too large (say, less than 150 GeV). Numerical results show that the branching ratios of B⃗Xsμ+μ- can be enhanced by more than 100% compared to the standard model (SM) and the backward-forward asymmetry of the lepton is significantly different from that in the SM when tan β⩾30. © 1998 The American Physical Society URL:
