Measurements of $\alpha_{s}$ from hadronic event shapes in $e^{+}e^{-}$ annihilation
New studies of hadronic event shape observables in e+ e- collisions between 13 and 183 GeV CM energy have enabled the running of alpha_s to be confirmed and the validity of non-perturbative power-law corrections to be investigated. A more precise value of alpha_s(M_Z) with reduced theoretical errors...
