Abstract

Production rates of multijet hadronic final states are studied in e+e-annihilation at 29 GeV center of mass energy. QCD shower model calculations with exact first order matrix element weighting at the first gluon vertex are capable of reproducing the observed multijet event rates over a large range of jet pair masses. The method used to reconstruct jets is well suited for directly comparing experimental jet rates with parton rates calculated in perturbative QCD. Evidence for the energy dependene of αsis obtained by comparing the observed production rates of 3-jet events with results of similar studies performed at higher center of mass energies. © 1989 Springer-Verlag.
