$B\to X_s{l}^{+}{l}^{-}$ in the left-right supersymmetric model

Abstract

We analyze the FCNC semileptonic decay $B\to X_s{l}^{+}{l}^{-}$ in a fully left-right supersymmetric model. We give explicit expressions for all the amplitudes involved in the process, and compare the numerical results with experimental bounds, in both the constrained case (where the only flavor violation comes from the Cabibbo-Kobayashi-Maskawa matrix) and the unconstrained case (including soft breaking supersymmetry terms). Stringent constraints on the parameter space of the model are obtained. We also include constraints from $b\to s\gamma$.
