DIRECT CP VIOLATION AT CERN The NA48 experiment at CERN reports a new detection of direct CP violation (partly responsible for the slight asymmetry between matter and anti-matter) in the decay of K mesons. The value they measure for the ratio epsilon prime over epsilon (roughly the ratio of direct to indirect CP violation--see Update 420) is 18.5±7 x 10^-4. The value reported by a Fermilab group earlier in the year was 28±4 x 10^-4. (http://www.cern.ch/Press; for background see Physics Today, May 1999.)
