✦ Synopsis

For the NA48 Collaboration

The direct CP violation parameter Re(e'/e) has been measured from the decay rates of neutral kaons into two pions using the NA48 detector at the CERN SPS. The 2001 running period data was collected under varied conditions compared to earlier years . The new data result is Re(e'/e) = (13.7 f 3.1) x 10e4. The overall value of Re(e'/e) = (14.7 f 2.2) x 10e4 is obtained from the complete NA48 data set.
