Abstract
An analysis of light vector meson photoproduction at small on the basis of the generalized parton distribution (GPD) approach is presented. Our results on the cross section and spin density matrix elements (SDME) are in fair agreement with DESY experiments. The predicted double spin longitudinal asymmetry is not small at HERMES energies.
