Isolated photon and photon+jet production at NNLO QCD accuracy

Chen, Xuan; Gehrmann, Thomas; Glover, Nigel; Höfer, Marius; Huss, Alexander

Abstract

We describe the calculation of the next-to-next-to-leading order (NNLO) QCD corrections to isolated photon and photon-plus-jet production, and discuss how the experimental hadron-level photon definition and isolation criteria can be approximated in the theoretical parton-level calculation. The NNLO corrections lead to a considerable reduction of the theory uncertainty on the predictions, typically to less than five per cent, and enable an improved description of experimental measurements from ATLAS and CMS.
