Abstract
We report on a measurement of the ratio of the strong coupling constan ts a, (Mo) for various data samples with different quark flavour compo sitions obtained from e+e- annihilation at LEP. We select events with muons, electrons, and D+/- mesons from charm and bottom decays, event s with highly energetic K(S)0 mesons originating predominantly from st range quarks, and events with highly energetic stable charged particle s from a combination of up, down and strange quarks. From the jet prod uction rates in these events we obtain from these samples the relative value of alpha(s) for the individual quark flavours as alpha(S)b/alph a(s)udsc = 1.017 +/- 0.036, alpha(S)c/alpha(S)udsb 0.918 +/- 0.115, al pha(S)s/alpha(S)udcb = 1.158 +/- 0.164, alpha(S)uds/alpha(S)cb 1.038 /- 0.221, with quadratically combined statistical and systematic error s. We also compare the a, values for quarks of different weak isospin, charge and generation. No evidence for a dependence of a, on any of t hese quark properties is observed. Finally, combining all samples and determining the alpha(s)f/alpha(s)incl ratio for each flavour, we do n ot find any dependence of the strong coupling constant on flavour.
