Abstract

The NA48 experiment at the CERN SPS accelerator aims to measure Re(epsilon'/epsilon), the direct CP violation parameter in K-0 --> 2 pi. decays, to the precision of 2 x 10(-4) In the year 1999, the NA48 collaboration has published its first measurement based on the 1997 data. The presented result is a preliminary measurement from data collected in the 1998 run which contain 2.5 times more K-L --> 2 pi (0) decays than the 1997 data. A combined result of Re(epsilon '/epsilon)=(14.0 +/-4.3) x 10(-4) has been obtained.
