Abstract

The value of the strong coupling constant, {Mathematical expression}, is determined from a study of 15 different observables in hadronic Z⁰ and τ decays. The study includes global event shape variables, jet production rates, energy correlations, the Z⁰ line shape and decay asymmetries and the hadronic branching fraction of τ-leptons. Differences between the α_s values from the different observables can be consistently attributed to unknown higher order contributions to the[Figure not available: see fulltext.] calculations. These uncertaities may be parametrized by variations of the renormalization scale and of the parton virtuality to which the data are corrected, separately for each observable, resulting in a consistent description of the event shapes, jet rates and energy correlations with the value {Mathematical expression} in[Figure not available: see fulltext.]. The error is dominated by the theoretical uncertainties. Application of recent calculations which include the resummation of leading and next-to-leading logarithms to all orders for some observables confirm this result with a reduced sensitivity to renormalization scale variations. The Z⁰ line shapes and τ-lepton branching ratios yield {Mathematical expression} and {Mathematical expression}, respectively, in[Figure not available: see fulltext.]. These measurements and their uncertainties are entirely independent of each other and from event shape and jet observables; the good agreement of the resulting α_s values thus constitutes an important consistency check of the reliability of perturbative QCD.

N2 - The value of the strong coupling constant, {Mathematical expression}, is determined from a study of 15 different observables in hadronic Z0 and τ decays. The study includes global event shape variables, jet production rates, energy correlations, the Z0 line shape and decay asymmetries and the hadronic branching fraction of τ-leptons. Differences between the αs values from the different observables can be consistently attributed to unknown higher order contributions to the[Figure not available: see fulltext.] calculations. These uncertaities may be parametrized by variations of the renormalization scale and of the parton virtuality to which the data are corrected, separately for each observable, resulting in a consistent description of the event shapes, jet rates and energy correlations with the value {Mathematical expression} in[Figure not available: see fulltext.]. The error is dominated by the theoretical uncertainties. Application of recent calculations which include the resummation of leading and next-to-leading logarithms to all orders for some observables confirm this result with a reduced sensitivity to renormalization scale variations. The Z0 line shapes and τ-lepton branching ratios yield {Mathematical expression} and {Mathematical expression}, respectively, in[Figure not available: see fulltext.]. These measurements and their uncertainties are entirely independent of each other and from event shape and jet observables; the good agreement of the resulting αs values thus constitutes an important consistency check of the reliability of perturbative QCD.
