Sommario:
- We apply the Euler transformation to accelerate the convergence of the QCD perturbative series with the aim to determine the strong coupling $α_s$ in terms of the total $τ$-decay rate $r_τ$. The variation of the result with the order of the QCD perturbation theory is small and comparable with the uncertainties of $r_τ$. We also present an estimate of a range of the yet unknown 5th and 6th order coefficients $k_5$ and $k_6$ of the Adler function.
