Photon isolation effects at NLO in γγ+jet final states in hadronic collisions


Gehrmann, T; Greiner, N; Heinrich, G (2013). Photon isolation effects at NLO in γγ+jet final states in hadronic collisions. Journal of High Energy Physics, 2013(6):17pp.

Abstract

We present the NLO QCD corrections to pp → γγj 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 γγj cross section on the photon isolation parameters.
