  • A review of the latest CPLEAR results on T violation and CPT invariance in the neutral-kaon system : presented at 4th International conference on hyperons, charm and beauty hadrons, Valencia, Spain, 27-30 June 2000
    Angelopoulos, A. ...
    The CPLEAR experiment has studied the symmetries which may exist between matter and antimatter by comparing the time evolution of K[sup]0 and K[bar][sup]0. A number of measurements allowed the ... determination, with high precision and in a rather complete way, of the parameters of the time evolution and the related symmetry properties. T and CPT could be disentangled from CP and the first direct measurement of T violation was performed. The CPT invariance was directly tested through the parameter Re([delta]), while Im([delta]) was best determined from the Bell-Steinberger relation. The K[sup]0 and K[bar][sup]0 mass and decay width defferences were then bound to less than a few times 10[sup]-18 GeV.
