New results from the NA48/2 experiment at CERN SPS: radiative nonleptonic kaon decays

Abstract

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 $K^{\pm }\to {\pi }^{\pm }{e}^{+}{e}^{-}$ decay candidates with 0.6% background, 1,164 $K^{\pm }\to {\pi }^{\pm }\gamma \gamma$ candidates with 3.3% background, and 120 $K^{\pm }\to {\pi }^{\pm }\gamma e^{+}{e}^{-}$ candidates with 6.1% background allowed precise measurements of branching fractions and other characteristics of these rare kaon decays.
