摘要：

We discuss the effect of CP-violating Zb ($) over bar b, Zb ($) over bar bG and Zb ($) over bar by couplings on the width Gamma(Z --> b ($) over bar bX). The presence of such couplings leads in a natural way to an increase of this width relative to the prediction of the standard model. Various strategies of a direct search for such CP-violating couplings by using CP-odd observables are outlined. The number of Z bosons required to obtain significant information on the couplings in this way is well within the reach of present LEP experiments.
