Automation of one-loop QCD computations

Primary tabs

Hirschi, Valentin Frederix, Rikkert Frixione, Stefano Garzelli, Maria Vittoria Maltoni, Fabio [UCL] Pittau, Roberto

We present the complete automation of the computation of one-loop QCD corrections, including UV renormalization, to an arbitrary scattering process in the Standard Model. This is achieved by embedding the OPP integrand reduction technique, as implemented in CutTools, into the MadGraph framework. By interfacing the tool so constructed, which we dub MadLoop, with MadFKS, the fully automatic computation of any infrared-safe observable at the next-to-leading order in QCD is attained. We demonstrate the flexibility and the reach of our method by calculating the production rates for a variety of processes at the 7TeV LHC.
