Understanding perturbative results for decays of τleptons into hadrons
arXiv:1212.5346 · doi:10.1134/S1063779613020147
Abstract
We review some results obtained by us and others concerning the structure of higher order perturbation series in perturbative QCD and their resummation using the renormalization group equation. We illustrate our results by a number of examples involving hadronic τdecays and e^+ e^- annihilation.
