Abstract
We reassess the theoretical uncertainties of strong-coupling determinations from a global fit to the thrust data, focusing in particular on the scheme dependence associated with the applied renormalon-cancellation prescription and on the choice of scale parameters that are used to estimate higher-order perturbative corrections in all sectors of the calculation.
