Abstract

Recent results on jet physics and on tests of perturbative QCD in hadronic final states of e+e- annihilations around the Z 0 pole are presented. Various jet algorithms are discussed in detail. Studies of 3- and 4-jet final states provide significant tests of the abelian nature of QCD, in particular for the gluon self coupling and for the running coupling constant αs (asypmptotic freedom). The coupling αs is determined, from studies of event topologies, jet production rates and from Z 0 line shapes and decay asymmetries, to be αs (M Z 0) = 0.119 ± 0.008. Studies of soft hadron and gluon coherence phenomena are shortly reviewed.
