Open Access item QCD predictions for the τ hadronic width: Determination of αs(Mτ^2)

Authors:Pich, Antonio
Issue Date:Mar-1995
Publisher:Elsevier
Citation:Nuclear Physics B Proceedings Supplements 39(2-3): 326-340 (1995)
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(Mτ^2) and its actual uncertainties are discussed.
