| Resumo | |
The mathematical method of Pade approximants is put forward to reconstruct the Borel transformed series of the Adler function and extract higher-order corrections in a model-independent way. The use of the D-log Pade approximants provides valuable information to its analytic structure and yields, together with the standard Pade approximants, reliable model-independent predictions of the higher-order coefficients, as for example, c(5)(,1) = 277 +/- 51. Such reconstruction strongly favours the use of fixed-order perturbation theory (FOPT) for the renormalization-scale setting. (AU) | |
