Search for direct CP violation in the decays K\pm \to 3π\pm

2 Collaboration, J. R. Batley

We report a measurement of the direct CP violation asymmetry parameter $A_g$ in charged kaon decays $K^{\pm }\to {\pi }^{\pm }{\pi }^{+}{\pi }^{-}$ by the NA48/2 experiment at the CERN SPS. The experiment h…
