QCD analysis of hadronic $\tau$ decays revisited
The calculation of perturbative corrections to the spectral moments observable in hadronic \tau decays is reconsidered. The exact order-\alpha_s^3 results and the resummation procedure of Le~Diberder and Pich are compared with a partial resummation of the perturbative series based on the analysis of...
