A precise measurement of the direct CP violation parameter $$\mathrm{Re}(\varepsilon'/\varepsilon)$$
Abstract
The direct CP violation parameter Re(ε'/ε) has been measured from the decay rates of neutral kaons into two pions using the NA48 detector at the CERN SPS. With 3.3 million K L → π0 π0 events collected during the 1998 and 1999 running periods, a result of Re(ε'/ε) = (15.0 ± 2.7) × 10-4 has been obtained. Finally, the result combined with the published 1997 sample is Re(ε'/ε) = (15.3 ± 2.6) × 10-4.
