A New Result on Direct CP Violation by NA48 at CERN
The NA48 collaboration at CERN has measured the direct CP violation parameter Re($\epsilon$′/$\epsilon$) from the decay rate of neutral kaons into two pions. During the 1998 and 1999 running periods, a result of Re($\epsilon$′/$\epsilon$) = (15.0 ± 2.7) × 10$^-4}$−4 has been obtained. The principles...
