Contribution
It provides the first comprehensive set of measurements of QCD colour factors at LEP, validating the SU(3) gauge symmetry of QCD.
Findings
Measurements are consistent with SU(3) predictions
Multiple methods yield compatible results
Supports the gauge group structure of QCD
Abstract
A summary of the measurements of the QCD colour factors at LEP is presented. Such measurements provide a test of the gauge group structure underlying the theory of strong interactions. A variety of methods have been applied by the various experiments, and perfect consistency with the expectation of QCD with SU(3) as gauge group is found.
