Spin Effects and Amplitude Structure in Vector Meson Photoproduction at Small $x$

High Energy Physics - Phenomenology 2007-05-23 v1

Abstract

An analysis of light vector meson photoproduction at small xx 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 ALLA_{LL} asymmetry is not small at HERMES energies.
