Dileptonic decay of B_s meson in SUSY models with large tanβ

Abstract

Decay of B_s meson into the dileptonic channels of e⁺e^- and μ⁺μ^- 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 tanβ, 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.
