Abstract (data abstract)
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. CERN and DESY.
