A universal Regge pole model for all vector meson exclusive photoproduction by real and virtual photons
Abstract
A model based on a dipole pomeron framework for exclusive vector meson photoproduction by real and virtual photons shows very good agreement with the experimental data. This model does not violate unitarity constraints and describes in a universal manner all the available data for ρ, ω, \varphi, J/ψ and Upsilon vector meson photoproduction in the region of energies 1.7le W le 250{ GeV} and photon virtualities 0 le Q^2 le 35{ GeV}^2.
