We consider \stackrel\ensuremath→BXsli+lj^\ensuremath- decays in the minimal supersymmetric standard model with explicit R-parity violation. From the present upper limits on the branching ratios for these processes, we obtain the constraints on the product combinations of the R-parity-violating couplings which are in many cases more severe than the previous ones. Taking into account the invariant dilepton mass spectrum and the forward-backward asymmetry of the emitted leptons, we show that the spectra and asymmetries obtained from R-parity-violating interactions are different from the SM ones. Therefore, they may be used in the future to disentangle R-parity-violating effects from the SM in these processes. We also show that it is possible to discriminate two types of R-parity-violating effects from each other. The general expectation of the enhancement of the forward-backward asymmetry of the emitted leptons in the minimal supersymmetric standard model with R parity may be corrupted by R-parity violation.
