Search for direct CP-violation in $K^{\pm} \to \pi^{\pm} \pi^{0} \pi^{0}$ decays
A search for direct CP-violation in $K^{\pm}\rightarrow \pi^\pm \pi^0 \pi^0$ decay based on 47.14 million events has been performed by the NA48/2 experiment at the CERN SPS. The asymmetry in the Dalitz plot linear slopes $A_g = ( g^+ -g^- ) / ( g^+ + g^- )$ is measured to be $A_g = (1.8 \pm 2.6) \cd...

| description | A search for direct CP-violation in $K^{\pm}\rightarrow \pi^\pm \pi^0 \pi^0$ decay based on 47.14 million events has been performed by the NA48/2 experiment at the CERN SPS. The asymmetry in the Dalitz plot linear slopes $A_g = ( g^+ -g^- ) / ( g^+ + g^- )$ is measured to be $A_g = (1.8 \pm 2.6) \cdot10^{-4}$. The design of the experiment and the method of analysis provide good control of instrumental charge asymmetries in this measurement. The precision of the result is limited by statistics and is almost one order of magnitude better than that of previous measurements by other experiments. |
