Messung der starken Kopplungskonstanten $\alpha_{s}$ und der hadronischen Spektralfunktionen in $\tau$-Zerfällen
The spectral functions of the vector current and the axial-vector current have been measured in hadronic tau decays using the OPAL detector at LEP. Within the framework of the operator product expansion a simultaneous determination of the strong coupling constant alpha /sub s/, the non-perturbative...
