Bs−B¯smixing,Bdecays andR-parity violating supersymmetry

We discuss the implications of the recent measurement of the B{sub s}-B{sub s} oscillation frequency {delta}M{sub s} on the parameter space of R-parity violating supersymmetry. For completeness, we also discuss the bounds coming from leptonic, semileptonic, and nonleptonic B decay modes, and point out some possibly interesting channels at the Large Hadron Collider.
