QCD tests with kaons
Final results from an analysis of about 400 $K^{\pm} \rightarrow \pi^{\pm}\gamma\gamma$ rare decay candidates collected by the NA48/2 and NA62 experiments at CERN are presented. The results include a model-independent decay rate measurement and fits to Chiral Perturbation Theory (ChPT) description....
