A study of ultraviolet renormalon ambiguities in the determination of $\alpha_{s}$ from $\tau$ decay
The divergent large-order behaviour of the perturbative series relevant for the determination of \as from \tau decay is controlled by the leading ultraviolet (UV) renormalon. Even in the absence of the first infrared (IR) renormalon, an ambiguity of order \Lambda^2/m_\tau^2 is introduced. We make a...
