摘要
Decay of B-s meson into the dileptonic channels of e(+)e(-) and mu(+)mu(-) are suppressed in the QCD corrected standard model due to the vector and axial nature of the coupling to lepton bilinears. We show that in SUSY theories with large tan beta, contributions to the amplitude arising out of exchange of neutral Higgs Bosons considerably enhances the decay of B-s into l(+)l(-). In some region of parameter space, the enhancement is more than two orders of magnitude, bringing it well within experimental possibilities in the near future.
