Abstract

The NA48 collaboration has performed an extensive study of rare kaon decays. In particular tests of Chiral Perturbation Theory have been done, using data from the Re() runs in 1998 and 1999 for K_L → π ^o γ γ and from the NA48/1 High Intensity for K_S → γ γ and for the first observation of K_S → π ^o γ γ
