Abstract
We analyse CP-violating effects in Z
4 jet
decays, assuming the
presence of a CP-violating effective triple gluon coupling. We discuss
the influence of this coupling on the decay width.
Furthermore, we analyse different CP-odd observables and propose strategies
of a direct
search for such a CP-violating GGG coupling. The present data of LEP 1
should give significant information on the coupling.
