| Resumo | |
We provide an overview of recent determinations of the strong coupling, as, from hadronic tau decays. We contrast two analysis methods, the "truncated-OPE approach" and the "DV-model approach," highlighting the assumptions going into each of these. We argue that a detailed study based on ALEPH data shows the truncated-OPE approach to be quantitatively unreliable, while the DV-model approach passes all tests. New data for hadronic tau decays from Belle and Belle-II could provide more stringent tests of the DV-model approach, and thus potentially lead to a more precise value alpha(s) of as from hadronic tau decays.
