Kaon physics overview

Abstract

The present status of Kaon physics is summarized from a theory point of view. Focus is laid on ΔS = 2, ΔS = 1 as well as on rare Kaon decays, where progress has been made for instance in the case of εK and KS → μ + μ − Furthermore, several New Physics scenarios are discussed in the context of rare Kaon decays and other Kaon observables.
