Abstract

The direct CP violation parameter Re(ε′/ε) has been measured from the decay rates of neutral kaons into two pions using the NA48 detector at the CERN SPS. With 3.3 million K_L → π⁰π⁰ events collected during the 1998 and 1999 running periods, a result of Re(ε′/ε) = (15.0 ± 2.7) × 10^-4 has been obtained. The result combined with the published 1997 sample is Re(ε′/ε) = (15.3 ± 2.6) × 10^-4.
