Photon Radiation with MadDipole
T. Gehrmann, N. Greiner
We present the automation of a subtraction method for photon radiation using the dipole formalism within the MadGraph framework. The subtraction terms are implemented both in dimen…
Modern Feynman Diagrammatic One-Loop Calculations
Thomas Reiter, Gavin Cullen, Nicolas Greiner +14
In this talk we present techniques for calculating one-loop amplitudes for multi-leg processes using Feynman diagrammatic methods in a semi-algebraic context. Our approach combines…
Recent Progress in the Golem Project
Gavin Cullen, Nicolas Greiner, Alberto Guffanti +10
We report on the current status of the Golem project which aims at the construction of a general one-loop evaluator for matrix elements. We construct the one-loop matrix elements f…
NLO QCD corrections to 4 b-quark production
Nicolas Greiner, Alberto Guffanti, Jean-Philippe Guillet +2
In this talk we present the recent calculation of the NLO QCD corrections to the production of four b-quarks induced by initial state quarks at the CERN LHC. We describe the detail…
Integrated dipoles with MadDipole in the MadGraph framework
Rikkert Frederix, Thomas Gehrmann, Nicolas Greiner
Heading towards a full automation of next-to-leading order (NLO) QCD corrections, one important ingredient is the analytical integration over the one-particle phase space of the un…
The SM and NLO multileg working group: Summary report
T. Binoth, G. Dissertori, J. Huston +88
This report summarizes the activities of the SM and NLO Multileg Working Group of the Workshop "Physics at TeV Colliders", Les Houches, France 8-26 June, 2009.
