Searching R-parity-violating supersymmetry in semileptonic B-decays

If R-parity is broken and the photino, although unstable, does not decay within the detector, then in new semileptonic B-decay modes a light (∼ 2–3 GeV) photino can be produced carrying missing energy. However, the photino, being massive, arranges a different kinematical configuration for the visible decay products as compared to a standard semileptonic event where the neutrino carries the missing energy. We study the above kinematic distributions in an attempt to explore the above scenario.
