Abstract.

We analyse CP-violating effects in Z \(\rightarrow\) 4 jet decays, assuming the presence of CP-violating effective \(Z b \bar{b} G\)$ and \(Z b \bar{b} G G\) couplings. We discuss the influence of these couplings on the decay width. Furthermore, we propose various strategies of a direct search for such CP-violating couplings by using different CP-odd observables. The present data of LEP 1 should give significant information on the couplings.
