Further tests of special interactions of massive particles from the Z polarization rate in $e^+e^-\to Zt\bar t$ and in $e^+e^-\to ZW^+W^-$
Résumé
We propose further tests of the occurence of scale dependent heavy particle masses (Z,W,t) and of strong final state interactions by comparing Z longitudinal polarization rates in different kinematical distributions of the $e^+e^-\to Zt\bar t$ and in $e^+e^-\to ZW^+W^-$ processes.
