Strong coupling constant from decay within renormalization scheme invariant treatment

J. G. Koerner, F. Krajewski, A. A. Pivovarov

We extract a numerical value for the strong coupling constant α_s from the τ-lepton decay rate into nonstrange particles. A new feature of our procedure is the explicit use of reno…
