Abstract

Recent results on diffraction at HERA, as measured by the H1 and ZEUS collaborations, are reviewed. Results on the photon-proton total hadronic cross section, on vector meson production both at small and large photon virtuality and on photon diffraction are presented. The experimental signature of diffraction at HERA, as well as the selection methods used by the two collaborations are explained.
