The NA48/2 experiment at the CERN SPS carried out data taking in 2003 and
2004. Analysis of the selected data samples of 7,146 K±→π±e+e−
decay candidates with 0.6% background, 1,164 K±→π±γγ
candidates with 3.3% background, and 120 K±→π±γe+e−
candidates with 6.1% background allowed precise measurements of branching
fractions and other characteristics of these rare kaon decays.Comment: Talk given at 22nd Rencontres de Physique de La Vallee d'Aoste, La
