T-violation and CPT-invariance measurements in the CPLEAR experiment: a
detailed description of the analysis of neutral-kaon decays to e pi nu

Αγγλικά

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-0 and (K) over bar (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 arc 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.
