Open Access item QCD Tests from Tau Decays

Authors:Pich, Antonio

Citation:Non-Perturbative Particle Theory and Experimental Tests: Proceedings (1997)
Abstract:The total $\tau$ 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 $\alpha_s(M_\tau^2)$ and its actual uncertainties are discussed.
