Automation of NLO calculations - Precise predictions for LHC processes — •Nicolas Greiner — Max-Planck-Institut fuer Physik, Foehringer Ring 6, 80805 Muenchen

The search for new physics is one of the main targets of the LHC. This requires an excellent understanding of the measurement and its uncertainties as well as precise predictions for signal and background on the theoretical side. Calculations at leading order in perturbation theory suffer from sizeable uncertainties leading to only imprecise predictions. Adding the next-to-leading order contributions improves the situation but the calculations become much more intricate. Therefore it is desirable to have such calculations done in an automated way in order to save time and avoid mistakes.

In this talk I will explain public tools that can be used for automated calcuations. Besides their description I will mainly focus on how they can be applied to relevant processes and present some results.
