Abstract
Recent results on the search for direct CP violation in the neutral kaon sy stem are discussed together with a review of the techniques used. The new p reliminary result from CERN-NA48 Re(epsilon '/epsilon) = (14.0 +/- 4.3) x 1 0(-4) is presented. The current world average is Re(epsilon '/epsilon) = (1 9.3 +/- 2,4) x 10(-4) establishing the existence of direct CP violation. (C ) 2001 Published by Elsevier Science B.V.
