Photon isolation effects at NLO in gamma gamma + jet final states in
hadronic collisions
   [PDF]

T. Gehrmann, N. Greiner, G. Heinrich
We present the NLO QCD corrections to diphoton plus jet production at hadron colliders. Our calculation includes contributions from the fragmentation of a hadronic jet into a highly energetic photon, and consequently allows the implementation of arbitrary infrared-safe photon isolation definitions. We compare different photon isolation criteria and perform a detailed study of the dependence of the diphoton plus jet cross section on the photon isolation parameters.
