Description
We present jet rates in hadronic decays of Z0 bosons measured by the SLD experiment at SLAC. The data are analyzed in terms of the JADE and recently proposed Durham algorithms, and are found to be in agreement with the predictions of perturbative QCD plus fragmentation Monte Carlo models of hadron production. Corrected 2, 3 and 4-jet rates are well described by ο(αs2) perturbative QCD calculations. From fits to the differential 2-jet distribution the strong coupling αs(MZ) is measured to be αs(MZ) = 0.119 ± 0.002(stat.) ± 0.003(exp.syst.) ± 0.014(theory) (preliminary). The largest contribution to the error arises from the theoretical uncertainty in choosing the QCD renormalisation scale
