On the ${\sigma }_L/{\sigma }_T$ Ratio in Polarized Vector Meson Photoproduction

Abstract

We study the spin-dependent cross-sections of vector meson photoproduction for longitudinally and transversely polarized photons within a QCD- model. The dependence of the ${\sigma }_T/{\sigma }_L$ ratio on the photon virtuality and on the meson wave function is analysed.
