  Rare Kaon decays and CP violation are important tools to test the Standard
Model and its extensions. We describe kaon physics observables testing CP
violation and more generally short distance physics. Channels under
consideration will be K -> pi nu nubar, K -> pi l+ l-, K+- > pi 3 pi, K+- ->
pi+- pi gamma, KS -> mu mu and K+- -> pi+- pi0 e+ e-
