abstract

• The NA62 measurement of the branching ratio and the di-photon mass spectrum of the K → π γγ decay is presented, together with a preliminary result on the branching fraction of the rare decay π0 → e e− . The first observation of the decay K± → π0π0µ±ν(K00 µ4 ) by the NA48/2 experiment at the CERN is also reported, together with the measurement of the branching ratio
