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


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+eK^\pm\to\pi^\pm e^+e^- decay candidates with 0.6% background, 1,164 K±π±γγK^\pm\to\pi^\pm\gamma\gamma candidates with 3.3% background, and 120 K±π±γe+eK^\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.Comment: Talk given at 22nd Rencontres de Physique de La Vallee d'Aoste, La Thuile, Aosta Valley, Italy, 24 Feb-1 Mar 2006. 15 pages, 4 figure
