A new measurement of direct CP violation in two pion decays of the neutral kaon

The NA48 experiment at CERN has performed a new measurement of direct CP violation, based on data taken in 1997 by simultaneously collecting KL and KS decays into π0π0and π+π-. The result for the CP violating parameter Re(ε′/ε′) is (18.5 ± 4.5(stat) ± 5.8(syst)) × 10-4. © 1999 Elsevier Science B.V....
