Abstract: (Elsevier)
We present a comprehensive review of the current theoretical and experimental status of rare kaon decays. The Standard Model contributions to K + → π + ν ν , K L → π 0 ν ν , and K L → π 0 ee are analyzed in detail, followed by a discussion of alternative theoretical frameworks that could modify the Standard Model predictions. Special attention is paid to “direct” super-symmetric flavor-changing neutral currents induced by renormalization-group scaling in minimal and in non-minimal supersymmetry. We review the theoretical motivations for the lepton number-violating decays K L → μ e and K + → π + μ e, and present bounds on the new interactions which mediate these processes. We describe the present cadre of rare kaon detectors, discuss the significance of their recent results, and assess to what extent their future results are likely to address the fundamental issues outlined above.
