  • A determination of the CPT violation parameter ▫$Re(\delta)$▫ from the tagged semileptonic decays of strangeness-tagged neutral kaons
    Angelopoulos, A. ...
    We have improved by two orders of magnitude the limit currently available for the CPT violation parameter Re([delta]). To this purpose we have analyzed the full sample of neutral-kaon decays to ... e[pi][nu] recorded in the CPLEAR experiment, where the strangeness of the neutral kaons was tagged at production and decay time. An appropriate function of the measured decay rates, including information from the analysis of [pi][sup]+[pi][sup]- decay channel, gives directly Re([delta]). The result Re([delta])=(3.0[plus minus]3.3[sub]stat[plus minus]0.6[sub]syst) x 10[sup]-4 is compatible with zero. Values for the parameters Im([delta]), Re(x[sub]-) and Im(x[sub]+) were also obtained.
