Description
We analyze the impact of using b-tagged samples in studying non-Abelian effects due to QCD in e+e-→4jet events at √s=MZ0, using angular variable analyses and comparisons with e+e-→3jetγ events. We find that QCD effects are largely enhanced in b-quark samples with respect to 'unflavoured' ones, where energy-ordering is used to distinguish between gluon and quark jets. We show that the b-quark mass influences the angular distributions significantly and should not be neglected. (orig.). With 11 figs., 2 tabs
