RADCOR 2009 - 9th International Symposium on Radiative Corrections

26 Oct 2009, 08:30 → 30 Oct 2009, 13:00 Europe/Zurich

Centro Stefano Franscini, Ascona

Gionata Luisoni, Radja Boughezal (University of Zurich), Thomas Gehrmann (Univ. Zurich)

Present and future particle colliders are able to measure fundamental scattering reactions with unprecedent experimental precision. Interpretation of these high-quality data demands an equally high theoretical precison, which is acheived through radiative corrections in quantum field theory. The symposium will especially focus precision physics in the upcoming CERN LHC era.
