  • T-violation and CPT-invariance measurements in the CPLEAR experiment: a detailed description of the analysis of neutral-kaon decays to ▫$e\pi\nu$▫
    Angelopoulus, A. ...
    A detailed description of the analysis of neutral kaons decaying to e[pi][nu] is given, based on the complete set of data collected with the CPLEAR experiment. Using a novel approach involving ... initially strangeness-tagged K[sup]0 and K[bar][sup]0, time-dependent decay-rate asymmetries were measured. These asymmetries enabled T- and CPT-violation parameters to be measured in the context of a systematic study. The highlights of this study are the first direct observation of T-violation and the direct determination of the CPT parameter Re([delta]) with an accuracy improved by two orders of magnitude with respect to the current value.
