Abstract

Jet production rates in hadronic Z⁰ decays are studied using four different recombination schemes to define resolvable jets. The strong coupling constant α_s( {Mathematical expression}) is determined in fits of the corresponding O(α_s ²) QCD calculations to the differential 2-jet distributions D₂(y). Hadronisation corrections and renormalisation scale uncertainties are found to be different for each recombination scheme. Within their overall systematic uncertainties, the four schemes yield consistent values of α_s( {Mathematical expression}), leading to a final result of {Mathematical expression}. The error includes the experimental uncertainties (±0.003), uncertainties of hadronisation corrections and of the degree of parton virtualities to which the data are corrected, as well as the uncertainty of choosing the renormalisation scale.

N2 - Jet production rates in hadronic Z0 decays are studied using four different recombination schemes to define resolvable jets. The strong coupling constant αs( {Mathematical expression}) is determined in fits of the corresponding O(αs 2) QCD calculations to the differential 2-jet distributions D2(y). Hadronisation corrections and renormalisation scale uncertainties are found to be different for each recombination scheme. Within their overall systematic uncertainties, the four schemes yield consistent values of αs( {Mathematical expression}), leading to a final result of {Mathematical expression}. The error includes the experimental uncertainties (±0.003), uncertainties of hadronisation corrections and of the degree of parton virtualities to which the data are corrected, as well as the uncertainty of choosing the renormalisation scale.
