We introduce a QCD coupling redefinition which has a simple scheme transformation. As an application, we discuss possible improvements on perturbative predictions of QCD physical quantities. In particular, we focus our attention to the Adler function, which is relevant for the extraction of αs from tau decays.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating
very compact bibliographies which can be beneficial to authors and
readers, and in "proceeding" format
which is more detailed and complete.
