Abstract | |||||||||||||
| The NA48 experiment at CERN has performed a new measurement of direct CP violation, based on data taken in 1997 00 qy Z X . by simultaneously collecting K and K decays into pp and pp. The result for the CP violating parameter Re r LS ZZ.Z.. y4 is 18.5"4.5 stat "5.8 syst =10 . q 1999 Elsevier Science B.V.
