| Abstract: | We apply the Euler transformation to accelerate the convergence of the QCD perturbative series with the aim to determine the strong coupling πΌπ in terms of the total π-decay rate ππ . The variation of the result with the order of the QCD perturbation theory is small and comparable with the uncertainties of ππ . We also present an estimate of a range of the yet unknown 5th and 6th order coefficients π5 and π6 of the Adler function. |
