مستخلص: | Abstract.: A detailed analysis of neutral kaons decaying to is presented based on the complete data set containing half a million events. Time-dependent decay rate asymmetries are measured between initially tagged and and for different regions of the phase space. These asymmetries, resulting from the interference between the CP-conserving decay amplitude of and the decay amplitude of – either CP-violating or CP-conserving – allow the determination of the parameters (CP-violating) and (CP-conserving), and also of the main isospin components of the decay amplitude. The branching ratio of (CP-conserving) is deduced directly from . In addition, we extract the slope parameters describing the energy dependence of the 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). |
