Photon plus jet cross sections in deep inelastic ep collisions at order O(α2αs) Original Research Article

The production of a hard and isolated photon accompanied by one or two jets in large- Q2 deep inelastic ep scattering is calculated at next-to-leading order. We include consistently contributions from quark-to-photon fragmentation and study various differential cross sections and their dependence on isolation cut parameters. Numerical results relevant for HERA experiments are presented.
