B-]X(S)L(I)(-) DECAYS WITH R-PARITY VIOLATION - ART. NO. 035006()L(J)()

We consider B --> X(s)l(i)(+)l(j)(-) decays in the minimal supersymmet ric standard model with explicit R-parity violation. From the present upper limits on the branching ratios for these processes, we obtain th e constraints on the product combinations of the R-parity-violating co uplings which are in many cases more severe than the previous ones. Ta king into account the invariant dilepton mass spectrum and the forward -backward asymmetry of the emitted leptons, we show that the spectra a nd asymmetries obtained from R-parity-violating interactions are diffe rent from the SM ones. Therefore, they may be used in the future to di sentangle R-parity-violating effects from the SM in these processes. W e also show that it is possible to discriminate two types of R-parity- violating effects from each other. The general expectation of the enha ncement of the forward-backward asymmetry of the emitted leptons in th e minimal supersymmetric standard model with R parity may be corrupted by R-parity violation.
