Measuring $\alpha_{s}$(Q$^{2}$) in $\tau$ decays
The decay rate of the \tau lepton into hadrons of invariant mass smaller than Q\gg\Lambda_{\rm QCD} can be calculated in QCD using the OPE. Using experimental data on the hadronic mass distribution, the running coupling constant \alpha_s(Q^2) is extracted in the range 0.85~\mbox{GeV}<Q<m_\tau,...
