A test of the flavour independence of the strong interaction for five flavours
Abstract
We report on a measurement of the ratio of the strong coupling constants$$\alpha _s (M_{Z^0 } )$$ for various data samples with different quark flavour compositions obtained frome+e− annihilation at LEP. We select events with muons, electrons, andD*± mesons from charm and bottom decays, events with highly energeticKs0 mesons originating predominantly from strange quarks, and events with highly energetic stable charged particles from a …
