Rare B meson decays in the Minimal R-symmetric Supersymmetric Standard Model

Abstract

Taking into account the constraints imposed by experimental data on the parameter space, we analyze the lepton flavor violating decays of B meson in the scenario of the minimal R-symmetric supersymmetric standard model. The prediction of the branching ratios is strongly affected by $\tan \beta$ and the off-diagonal entries in the slepton and squark mass matrices. The off-diagonal entries in the slepton mass matrix are constrained by the experimental limits of radiative two body decays of leptons. The off-diagonal entries in the squark mass matrix are constrained by the experimental limits of low energy observables related to B meson physics. The branching ratio of $B_d^0\to \mu \tau$ is predicted to be four orders of magnitude below the future experimental sensitivity and the decay $B_d^0\to \mu \tau$ has a higher chance of being observed in the future.
