Abstract

Hadronic jet production by e⁺e^--annihilation has been studied in the energy range of 14.0-46.7 GeV. The data have been analysed in terms of a cluster algorithm and other topological quantities. The results are compared with 2^nd order QCD calculations which incorporate models for the fragmentation of quarks and gluons into hadrons. At the higher energies we observe more spherical and 4-jet like events than predicted by these calculations. We cannot achieve a simultaneous description of the observed 3- and 4-jet production by adjusting the strong coupling constant α_s or the fragmentation parameters of the 2^nd order QCD models. The observed excess of spherical events can partially be explained by the production of multi-parton events expected from higher order QCD contributions. Consequences of the presented results for the value of α_s, determined in previous analyses, are discussed. QCD parton shower models, including soft gluon interference, are able to describe the observed number of spherical events.
