QCD Tests from Tau Decays
A. Pich
Abstract
The total τ hadronic width can be accurately calculated using analyticity and the operator product expansion. The theoretical analysis of this observable is updated to include all available perturbative and non-perturbative corrections. The experimental determination of αs(Mτ2) and its actual uncertainties are discussed.
