QCD Measurements in e+e- Annihilations at Centre-of-Mass Energies between 91 and 206 GeV

Consistent measurements of event-shape variables and alpha_s using the complete set of data taken with the ALEPH detector at LEP are presented. The strong coupling constant is determined from a fit of O(alpha_s^2)+NLLA QCD calculations to distributions of 6 event-shape variables at 8 centre-of-mass...

description Consistent measurements of event-shape variables and alpha_s using the complete set of data taken with the ALEPH detector at LEP are presented. The strong coupling constant is determined from a fit of O(alpha_s^2)+NLLA QCD calculations to distributions of 6 event-shape variables at 8 centre-of-mass energies. Combined results are compared to the expected evolution of alpha_s.
