Abstract:We carry out a systematic analysis of ΔB = 2 interactions in supersymmetric theories. The selection rules in ΔB = 2 transition depend on the relative value of M (the mass scale that characterizes the ΔB = 2 interactions) and Λs (the super-symmetry-breaking scale). In particular, if M ? 104GeV and Λs ~ 102GeV, the effective ΔB = 2 interactions induce NN annihilation in a nucleus yielding two kaons in the final state while processes with only one or zero kaons are suppressed by mixing angles. On the other hand, if M ? 104GeV, then supersymmetry does not imply any additional selection rules beyond those of ordinary (non-supersymmetric) theories.
