CPLEAR results on the CP parameters of neutral kaons decaying to $\pi^+ \pi^- \pi^0$
The CPLEAR experiment measured time-dependent decay-rate asymmetries of \PKz\ and \PaKz\ decaying to \pipmz\ in order to study the interference between the decay amplitudes of \PKzS\ --- either CP-violating or CP-conserving --- and the CP-conserving \PKzL\ decay amplitude. From the analysis of the c...

| description | The CPLEAR experiment measured time-dependent decay-rate asymmetries of \PKz\ and \PaKz\ decaying to \pipmz\ in order to study the interference between the decay amplitudes of \PKzS\ --- either CP-violating or CP-conserving --- and the CP-conserving \PKzL\ decay amplitude. From the analysis of the complete data set we find for the CP-violating parameter \etapmz , % % $ \reeta = \left( -2 \pm 7 \mbox{\rm \ stat.\ } ^{+4}_{-1} \mbox{\rm \ syst.} \right) \times 10^{-3} , $ $ \imeta = \left( -2 \pm 9 \mbox{\rm \ stat.\ } ^{+2}_{-1} \mbox{\rm \ syst.} \right) \times 10^{-3} $ % % and for the CP-conserving parameter \lampmz , % % $ \relam = \left(+28 \pm 7 \mbox{\rm \ stat.\ } \pm 3 \mbox{\rm \ syst.} \right) \times 10^{-3} , $ $ \imlam = \left( -10 \pm 8 \mbox{\rm \ stat.\ } \pm 2 \mbox{\rm \ syst.} \right) \times 10^{-3}. $ % % From the latter, the branching ratio of the CP-conserving $\PKzS \rightarrow \pipmz $ decay is deduced to be % % $ \mathrm{B} = \left( 2.5 ^{+1.3}_{-1.0} \mathrm{\ stat.\ } ^{+0.5}_{-0.6} \mathrm{\ syst.\ } \right) \times 10^{-7}. |
