Photoproduction of isolated photons at HERA in NLO QCD
Maria Krawczyk
Abstract
The NLO QCD calculation for the photoproduction of the isolated photon with a large pT at the HERA ep collider is presented. The single resolved photon contribution and the QCD corrections of order αs to the Born term are consistently included. The sizeable NNLO contributions, the box and the double resolved photon subprocesses, are taken into account in addition. The importance of the isolation cut, as well as the influence of other experimental cuts on the pT and rapidity etagamma distributions are discussed in detail. Results are compared with experimental data and with the different NLO calculations.
