Probing the Flavor and CP Structure of Supersymmetry with K --> pi Neutrino Anti-neutrino Decays


We study the implications of various supersymmetric models on the rare $K^+ \to \pi^+ \nu \bar\nu$ and $K_L \to \pi^0 \nu \bar\nu$ decays. Although large effects are possible in generic \susic\ models, most of the known \susic\ flavor models lead to negligible effects. Thus, it is likely that one can get information about CKM matrix elements from these decays even in the presence of \susy. Moreover, the possibility of large contributions to \kpnn\ in generic \susy\ models can be constrained by improved bounds on $D-\bar D$ mixing. We show that it may be possible to distinguish between different \susic\ flavor models by combining the information from the \kpnn\ decays with that from $B-\bar B$ and $D-\bar D$ mixing.
