$K^{0}-\overline{K}^{0}$ mass and decay-width differences: CPLEAR evaluation
The CPT-violation parameters \redd\ and \imd\ determined recently by CPLEAR are used to evaluate the \kn --\knb\ mass and decay-width differences, as given by the difference between the diagonal elements of the neutral-kaon mixing matrix $({\mathrm M}-\i\Gamma/2)$. The results --- $({\mathrm M}_{\kn...

| description | The CPT-violation parameters \redd\ and \imd\ determined recently by CPLEAR are used to evaluate the \kn --\knb\ mass and decay-width differences, as given by the difference between the diagonal elements of the neutral-kaon mixing matrix $({\mathrm M}-\i\Gamma/2)$. The results --- $({\mathrm M}_{\kn\kn}-{\mathrm M}_{\knb\knb}) = ( -1.5 \pm 2.0 )\times10^{-18}$ \gev\ and $(\Gamma_{\kn\kn}-\Gamma_{\knb\knb}) = ( 3.9 \pm 4.2 )\times 10^{-18}$ \gev\ --- are consistent with CPT invariance. The CPT invariance is also shown to hold within a few times $10^{-3}-10^{-4}$ for many of the amplitudes describing neutral-kaon decays to different final states. |
