For a quantitative analysis of the non-Abelian three-gluon vertex a continuous parameterisation of possible deviations from QCD is highly desirable. An almost unique extension of the three-gluon vertex is provided by the dimension-6 operator Tr(FμνFνρFρμ). The effects of this interaction term on various observables ine+e−→γ,Z→4 jet production are studied in detail. Presente+e− data are expected to give rather weak bounds on such anomalous contributions to the triple gluon vertex.
