The measure epsilon' of direct CP violation in K → ππ decays disagrees with the Standard-Model prediction by 2.8 standard deviations. It is possible to explain this discrepancy with supersymmetric contributions involving squarks and gluinos in the multi-TeV range. I discuss the footprint of this scenario on the rare decays K+ → π+ ν ν̄ and KL → π0 ν ν̄.
