Abstract: The electron–proton collider HERA at DESY opened the door for the study of diffraction in real and virtual photon–proton scattering at centre-of-mass energies W up to 250 GeV and for large negative mass squared − Q 2 of the virtual photon up to Q 2 = 1600 GeV 2 . At W = 220 GeV and Q 2 = 4 GeV 2 , diffraction accounts for about 15% of the total virtual photon–proton cross section, decreasing to ≈5% at Q 2 = 200 GeV 2 . An overview of the results obtained by the experiments H1 and ZEUS on the production of neutral vector mesons and on inclusive diffraction up to the year 2008 is presented.
