Abstract

Physics and Astronomy (miscellaneous)

Multihadron events produced by e+e- annihilation at a c.m. energy of 34.6 GeV have been used to determine αs. The predictions of 1 st and 2nd order QCD models with independent jet and string fragmentation have been compared to a large variety of kinematic variables such as event shapes, transverse momentum spectra, jet masses, 3-cluster thrust and the asymmetry of energy-energy correlations. The value of αs has been found to depend on the variables used, on the fragmentation model and on the treatment of soft gluons in the 2nd order QCD calculation. Within the models considered αs has been found in complete 2nd order QCD to lie between 0.12 and 0.23.
