The NA48 collaboration at CERN has measured the direct CP violation in two pion decays of neutral kaons. The CP violation parameter 0/ = (15.3 ± 2.6) × 10-4 is the result of three years of data taking (1997, 1998, 1999). The experiment principles, the data analysis features and the systematic error evaluation will be described. The result by the FNAL KTEV collaboration will also be quoted.

Abstract
The NA48 collaboration at CERN has measured the direct CP violation in two pion decays of neutral kaons. The CP violation parameter 0/ = (15.3 ± 2.6) × 10-4 is the result of three years of data taking (1997, 1998, 1999). The experiment principles, the data analysis features and the systematic error evaluation will be described. The result by the FNAL KTEV collaboration will also be quoted.
