High-pT photon processes and the photon structure - results from HERA   jet and prompt photon (photo)production
  Many important QCD tests with jets and prompt photons have been performed with the experiments H1 and ZEUS at the HERA ep collider. This contribution focuses on results from jet and prompt photon photoproduction. In particular, the concept of resolved photon interactions and various jet cross sections and their sensitivity to the photon (and proton) PDFs will be discussed. In addition, recent results from prompt photon production will be shown. Finally results on multi-parton interactions and the underlying event will be presented.
