Abstract
We have measured the ratio of the strong coupling constants αS for bottom quarks and light quarks at the Z0 resonance, in order to test the flavour independence of the strong interaction. The coupling strength αS has been determined from the fraction of events with three jets, measured for a sample of all hardronic events, and for inclusive muon and electron events. The b purity is evaluated to be 22% for the first data set and 87% for the inclusive lepton sample. We find αS (b)/αS(udsc) = 1.00 ± 0.05 (stat.) ± (0.06) (syst.).
