Baryonic b arrow right sll transition decays

Flavor changing neutral current decays of B meson mediated via b arrow right sll transition process, where l represents an electron, a muon, or a tau lepton, provide promising probes for physics beyond the standard model. In this context, we use the most general effective Hamiltonian for b arrow right sll process and study the branching ratio and various asymmetries of B- arrow right [Lambda] p mu super(+) mu super(-) four body baryonic decays of B meson. We also see the effect of various new physics couplings in this decay mode. Within the standard model, the branching ratio of B- arrow right [Lambda] p mu super(+) mu super(-) decay mode is found to be 1.08 x 10 super(-7) and hence can be tested in the forthcoming or future B factories.
