Abstract
Selected recent results on diffractive vector-meson production from the H1 and ZEUS experiments at the HERA ep collider are reviewed and compared with the predictions of the vector-meson dominance model and of perturbative QCD. The helicity structure and energy dependence are studied for production of light and heavy vector mesons across a range of the photon virtuality Q 2 and the squared four-momentum transfer t. The cross section for elastic photoproduction of Ψ is also presented.
