New measurement of direct CP violation by NA48 at CERN
The measurement of the direct CP violation in the neutral kaon system has been performed by the NA48 collaboration at the CERN SPS. The result of $\Re(\epsilon '/\epsilon)$ from the 98 and 99 data is $(15.0 \pm 2.7) \times 10^{-4}$, which confirms the existence of a direct CP violation.
