Analytic Perturbation Theory and Inclusive Tau Decay
K. A. Milton, I. L. Solovtsov, O. P. Solovtsova
Abstract
We apply analytic perturbation theory to the inclusive decay of a τ lepton into hadrons. It is shown that the resulting analyticity of the coupling constant strongly influences the value of the QCD Λ-parameter extracted from the experimental data on τ decay.
