CP Violation in Decays Z --> 4 Jets

Abstract

We analyse CP-violating effects in Z \to 4 jet decays, assuming the presence of CP-violating effective $Zb\bar{b}G$ and $Zb\bar{b}GG$ 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.
