Summary
We summarize the results on deep inelastic scattering and photoproduction from ZEUS, one of the two detectors at the HERA electron-proton collider. At the deep-inelastic-scattering regime, we report on a measurement of the proton structure functionF 2. We discuss jet production and the observation of a new class of events with a large rapidity gap between the struck quark and the proton. In the photoproduction regime, we present evidence for hard-scattering processes and jet production, in particular in resolved photon processes.
