摘要：
A new measurement of Re(epsilon'/epsilon) by the NA48 collaboration using data collected in 1998 is presented. The preliminary result is Re(epsilon'/epsilon) = (12.2 +/- 2.9 (stat) +/- 4.0 (sys)) x 10(-4). The combination with the previous measurement using the 1997 data yields Re(epsilon'/epsilon) = (14.0 +/- 4.3) x 10(-4). This result confirms the existence of dirt CP violation. The uncertainty on this measurement will be improved in the future.
