Abstract

We report on a measurement of the ratio of the strong coupling constants {Mathematical expression} for various data samples with different quark flavour compositions obtained from e+e- annihilation at LEP. We select events with muons, electrons, and D mesons from charm and bottom decays, events with highly energetic Ks 0 mesons originating predominantly from strange quarks, and events with highly energetic stable charged particles from a combination of up, down and strange quarks. From the jet production rates in these events we obtain from these samples the relative value of αs for the individual quark flavours as {Mathematical expression} with quadratically combined statistical and systematic errors. We also compare the αs values for quarks of diffrent weak isospin, charge and generation. No evidence for a dependence of αs on any of these quark properties is observed. Finally, combining all samples and determining the αs fs incl ratio for each flavour, we do not find any dependence of the strong coupling constant on flavour.

N2 - We report on a measurement of the ratio of the strong coupling constants {Mathematical expression} for various data samples with different quark flavour compositions obtained from e+e- annihilation at LEP. We select events with muons, electrons, and D*± mesons from charm and bottom decays, events with highly energetic Ks 0 mesons originating predominantly from strange quarks, and events with highly energetic stable charged particles from a combination of up, down and strange quarks. From the jet production rates in these events we obtain from these samples the relative value of αs for the individual quark flavours as {Mathematical expression} with quadratically combined statistical and systematic errors. We also compare the αs values for quarks of diffrent weak isospin, charge and generation. No evidence for a dependence of αs on any of these quark properties is observed. Finally, combining all samples and determining the αs f/αs incl ratio for each flavour, we do not find any dependence of the strong coupling constant on flavour.
