| Abstract: | We analyze the impact of usingb-tagged samples in studying non-Abelian effects due to QCD ine + e ? → 4jet events at √s=M z 0, using angular variable analyses and comparisons withe + e ? → 3jetγ events. We find that QCD effects are largely enhanced inb-quark samples with respect to ‘unflavoured’ ones, where energy-ordering is used to distinguish between gluon and quark jets. We show that theb-quark mass influences the angular distributions significantly and should not be neglected. |
