title: "Table 2" of "QCD analyses and determinations of alpha(s) in e+ e- annihilation at energies between 35-GeV and 189-GeV."

description: Weighted mean for ALPHAS at the Z0 mass determined from the energy evolutions of the mean values of the 2-jet cross sections obtained with the JADE and DURHAMschemes and the 3-jet fraction for the JADE, DURHAM and CAMBRIDGE schemes evaluted at a fixed YCUT.. The errors shown are total errors and contain all the statistics and systematics.
description: CERN and DESY. Measurments of jet-multiplicity related observables in E+E- annihilations in the c.m. energy range from 35 to 189 GeV using data taken by the JADE and OPAL experiments. The observables are obtained using the JADE, Durham, Cambridge and cone finding jet alogrithms. The observables measured are the N-jet rates, the mean jet multiplicities, the differential cross sections w.r.t. Yn,n+1 and the differential N-jet fractions. The strong coupling constant ALPHAS is determined at each energy by fits to O(alpha_s**2) calculations, as well as matched O(alpha_s**2) and NLLA predictions to the data.. This is PART 1 of the record and gives the ALPHAS results. PART 2 gives the measured observables using the JADE jet finding alogrithm. PART 3 gives the measured observables using the DURHAM jet finding alogrithm. PART 4 gives the measured observables using the CAMBRIDGE jet finding alogrithm. PART 5 gives the measured observables using the CONE jet finding alogrithm. Numerical values supplied by P Pfeifenschneider.
