Abstract: In the presentation, Matthias will aim to provide a brief overview of his recent scientific interests, namely precision low-energy QCD and determination of Standard Model parameters. As a prime example, hadronic decays of the tau lepton shall be discussed which are a promising source to determine the strong QCD coupling. A precise extraction is obstructed by the presumable divergence of perturbative series in Quantum Field Theory. Strategies to overcome this complication will be touched upon. As usual we will offer fruits, snacks and soft drinks in the lounge area. Matthias Jamin is a Cluster guest. Local host: Martin Beneke (TUM)
