This webpage contains the package for calculating the next-to-leading order QCD corrections to diphoton + jet.

The package is based on

"Photon Isolation effects at NLO in gamma gamma + jet final states in hadronic collisions"
  T.Gehrmann, N.Greiner, G.Heinrich, arxiv:1303.0824

  • based on GoSam + MadDipole + MadGraph/MadEvent
  • cone isolation and Frixione isolation are implemented
  • output format: histograms (txt file)
