N³LO-renormalon-inspired resummations and fully analytic infra-red freezing in perturbative QCD

We make use of the recent calculation of d3 by Baikov, Chetrykin and Kuhn of N3LO QCD vacuum polarization to analyze the inclusive tau-decay ratio Rτ . We perform an all-orders resummation of the QCD Adler D function for the vector correlator, in which the part of perturbative coefficients containin...
