$B_{s,d}^0\to l^{+}{l}^{-}$ in the minimal gauged $(B-L)$ supersymmetry

Abstract

Complete expressions of effective Hamilton for $b\to s{l}^{+}{l}^{-}(l=\mu ,\tau )$ are derived in the framework of minimal supersymmetric extension of the standard model with local $B-L$ gauge symmetry. With some assumptions on parameters of the model, a numerical analysis of the supersymmetric contributions to the branching ratios of $B_s^0\to l^{+}{l}^{-}(l=\mu ,\tau )$ is presented.
