| dc.description | Recent results on jet physics and tests of QCD from hadronic final states in $e^+e^-$ annihilation at PETRA and at LEP are reviewed, with special emphasis on hadronic event shapes, charged particle production rates, properties of quark and gluon jets and determinations of $α_s$. The data in the entire energy range from PETRA to LEP-2 are in broad agreement with the QCD predictions. The world summary of measurements of $α_s$ is updated and a detailed discussion of various methods to determine the overall error of $α_s (M_Z)$ is presented. The new world average is $α_s (M_Z) = 0.119 \pm 0.004$. The size of the error depends on the treatment of correlated uncertainties. | |
