Abstract

The direct CP violation parameter Re(ε'/ε) has been measured from two-pion decays of neutral kaons by the NA48 experiment at CERN SPS. The analysis of a new data sample, collected in 2001 under different conditions compared to earlier years (1997–99), provide the result: Re(ε'/ε) = (13.7 ± 3.1) × 10^−4. Combining this result with that published from 1997-98-99 data, we obtain an overall value Re(ε'/ε) = (14.7 ± 2.2) × 10^−4 from the NA48 experiment.
