Abstract

From 1 105 045 hadronic Z⁰ decays observed with the OPAL detector at the LEP e⁺e^- collider, 21 732 four-jet events are selected. A simultaneous 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) expectations of C_A/C_F=9/4 and T_F/C_F=3/8.

N2 - From 1 105 045 hadronic Z0 decays observed with the OPAL detector at the LEP e+e- collider, 21 732 four-jet events are selected. A simultaneous fit of three selected angular variables from these events by the second order QCD matrix element calculation yields CA/CF=2.11±0.16(stat.)±0.28(syst.)T F/CF=0.40±0.11(stat.)±0.14(syst.) for the ratios of colour factors, in agreement with SU(3) expectations of CA/CF=9/4 and TF/CF=3/8.
