Search for direct CP violation in $K^{\pm} \to \pi^{\pm}\pi^{+}\pi^{-}$ decays by NA48/2
First preliminary measurement of the direct CP-violating parameter Ag by the NA48/2 experiment at CERN SPS is presented. Using more than 1.6 billions of charged kaon decays into three charged pions, the charge asymmetry in the $K^{\pm} \to \pi^{\pm}\pi^{+}\pi^{-}$ Dalitz plot slope, Ag, has been mea...
