epsilon '/epsilon and rare K decays in the Standard Model and Supersymmetry

After briefly reviewing the status of epsilon'/epsilon in the Standard Mode l, I discuss SUSY contributions to epsilon'/epsilon, K+ --> pi (+)v (v) ove r bar, K-L --> pi (0)v (v) over bar and KL -> pi (0)e(+)e(-). While in the simplest case of the MSSM with Minimal Flavour Violation the main effect is a suppression of these transitions with respect to the Standard Model, lar ge enhancements are possible in more general SUSY models, with interesting correlations among the different processes.
