Automation of one-loop QCD computations


Hirschi, V; Frederix, R; Frixione, S; Vittoria Garzelli, M; Maltoni, F; Pittau, R (2011). Automation of one-loop QCD computations. Journal of High Energy Physics, (5):44.

Abstract

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 7 TeV LHC.
