Abstract
From 1 105 045 hadronic Z(0) decays observed with the OPAL detector at the LEP e(+)e(-) collider, 21 732 four-jet events are selected. A sim ultaneous fit of three selected angular variables from these events by the second order QCD matrix element calculation yields C-A/C-F = 2.11 +/- 0.16(stat.) +/- 0.28(syst.) T-F/C-F = 0.40 +/- 0.11(stat.) +/- 0. 14(syst.) for the ratios of colour factors, in agreement with SU(3) ex pectations of C-A/C-F = 9/4 and T-F/C-F = 3/8.
