Direct CP Violation in Neutral Kaon Decays


Abstract. The final result is presented of the NA48 experiment, performed at the CERN SPS neutral kaon beams, on the direct CP violation parameter Re(ε′/ε), as measured from the decay rates of neutral kaons into two pions. The data collected in years 1997-2001 yield the evidence for the direct CP violation with Re(ε′/ε) = (14.7± 2.2) × 10. Description of… (More)
