Review of Chiral Perturbation Theory experimental results in kaon decays

Chiral Perturbation Theory, as a low-energy effective field theory of strong interactions, is a very useful tool to study the interactions of kaons. Both in the semileptonic sector and in the non-leptonic one, several results have been achieved by NA48, KTeV, KLOE and ISTRA+. Recent results from both neutral and charged kaons are reviewed.
