dc.description.abstract We present a simple formulation of the inclusive and exclusive semi-hadronic decays of the tau lepton using QCD-duality finite energy sum rules (FESRs). We find that the tau decay is a good laboratory for measuring the QCD scale Lambda. Within the present experimental accuracy, we obtain LambdaMS ⋍ 100-200 MeV to four loops. This prediction can be sensibly improved once the experimental situation has been clarified.
