Recent results of the NA48/2 experiment

NA48/2 collected the wolrd largest sample of K± --+ 7r±7ro'Y decays. Direct Emission (DE) and Interference (INT) fractions with respect to the internal bremsstrahlung (IB) have been measured in the range 0 < T; < 80 MeV: FracnE(O < T; < 80 MeV) = (3.32 ± 0.15sta ± 0.14sys) X 10-2 Frac1NT(O < T; < 80 MeV) = -(2.35 ± 0.35sta ± 0.39sys) X 10-2 where T; is the kinetic energy of the charged pion in the kaon rest frame. A sample of 7253 K± --+ 7r±e+ e- decay candidates has been collected by the NA48/2 experiment. The branching ratio in the full kinematic range was measured to be BR = (3.11 ± 0.12) · 10-1. For both decays CP violating asymmetry has been studied.
