Ringberg workshop on non-perturbative QCD of jets

8 Jan 2007, 09:00 → 10 Jan 2007, 12:00 Europe/Zurich

Schloss Ringberg

Stefan Kluth (Max-Planck-Institut für Physik, Munich, Germany)

The understanding of hadron formation in the envoriment of high energy jets produced at e+e-, ep, or pp(pbar) colliders is a great challenge for theory and experiment. Various approaches exist from Monte Carlo models to analytic QCD based models to attempts at calculations from first principles. Knowlegde on the non-perturbative QCD of jets has direct impact on interpretation of Tevatron or LHC data and precision measurements at hadron colliders.
