摘要：
A large fraction of 4-jet events in Z0 decays evolve from qqBARgg parton states. These configurations allow us to test the triple gluon coupling which is a consequence of the non-Abelian nature of QCD. The strength and the form of this coupling determine the quark-gluon decomposition of the final state as well as angular correlations between the jets. A critical assessment of the sensitivity of these observables to the ggg vertex is presented under realistic experimental conditions. Methods to improve the sensitivity in large samples of Z0 decays are suggested.
