الوصف: A detailed analysis of neutral kaons decaying to \(\pi^{+}\pi^{-}\pi^{0}\) is presented based on the complete data set containing half a million events. Time-dependent decay rate asymmetries are measured between initially tagged \({\mathrm{{K}\mbox{}^0}}\) and \({\mathrm{\overline{K}\mbox{}^0}}\) and for different regions of the phase space. These asymmetries, resulting from the interference between the CP-conserving decay amplitude of \({\mathrm{K_L}}\) and the decay amplitude of \({\mathrm{K_S}}\)– either CP-violating or CP-conserving – allow the determination of the \({\mathrm{K_S}}\) parameters \(\eta_{+-0}\) (CP-violating) and \(\lambda\) (CP-conserving), and also of the main isospin components of the \({\mathrm{K_S}}\) decay amplitude. The branching ratio of \({\mathrm{K_S}}\rightarrow \pi^{+}\pi^{-}\pi^{0}\) (CP-conserving) is deduced directly from \(\lambda\). In addition, we extract the slope parameters describing the energy dependence of the \({\mathrm{K_L}} \rightarrow \pi^{+}\pi^{-}\pi^{0}\) Dalitz plot. The whole set of our results fits well within the current phenomenological picture of the neutral-kaon system including CP violation and Chiral Perturbation Theory (ChPT).
