Final QCD results from LEP
H. Stenzel
Abstract
Recent results on QCD studies in e+e- annihilations at LEP are presented. Data recorded by the LEP experiments at centre-of-mass energies between 91.2 to 206 GeV are included. The main topic is the measurement of alphas from event-shape variables and associated aspects like the energy evolution or non-perturbative power-law corrections. These 'standard' measurements are complemented by new determinations using the 4-jet rate with an excellent precision. A summary of the results on QCD colour factors from angular correlations in the 4-jet system completes this report.
