Automation of one loop calculations with GoSam
Nicolas Greiner (Max Planck Institut für Physik, München)

Reliable predictions for processes relevant at the LHC requires at least the calculation of next-to-leading order QCD corrections. For multi-particle final states this is a highly non-trivial task. Automating such calculations drastically simplifies these computations.
In this talk I will give an introduction to GoSam, a public package that can be used for automated generation of one-loop amplitudes. Besides the description of the package I will explain how it can be applied to relevant processes and present some results.
