CP violation and the widthZ→b $$\bar b$$

AbstractWe discuss the effect of CP-violatingZb $$\bar b$$ Zb $$\bar b$$ G andZb $$\bar b$$ γ couplings on the width Γ(Z→b $$\bar b$$ X). 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 ofZ bosons required to obtain significant information on the couplings in this way is well within the reach of present LEP experiments.
