Chen, Xuan and Gehrmann, Thomas and Glover, Nigel and Höfer, Marius and Huss, Alexander (2020) 'Isolated photon and photon+jet production at NNLO QCD accuracy.', Journal of high energy physics., 2020 (4). p. 166.
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.
