    AbstractThe 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(\(\varepsilon'/\varepsilon\)) runs in 1998 and 1999 for KL → πoγγ and from the NA48/1 High Intensity for KS → γγ and for the first observation of KS → πoγγPACS: 13.20.Eb Decays of K mesons – 14.40.Aq π, K and η mesons
