A study of the recombination scheme dependence of jet production rates and of αs() in hadronicZ0 decays
Abstract
Jet production rates in hadronicZ0 decays are studied using four different recombination schemes to define resolvable jets. The strong coupling constant αs($$M_{Z^0 } $$) is determined in fits of the correspondingO(αs2) QCD calculations to the differential 2-jet distributionsD2(y). Hadronisation corrections and renormalisation scale uncertainties are found to be different for each recombination scheme. Within their overall systematic …
