TTP00-02 Photon Plus Jet Cross Sections in Deep Inelastic $ep$ Collisions at Order $O(\alpha^2 \alpha_s)$

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.
