A universal Regge pole model for all vector meson exclusive photoproduction by real and virtual photons

A model based on a dipole Pomeron framework for vector meson exclusive photoproduction by real and virtual photons shows very good agreement with the experimental data. The model does not violate unitarity constrains and describes in a universal manner all the available data for $\rho$, $\omega$, $\varphi$, $J\mathrm{/}\psi$ and $\mathrm{{\rm Y}}$ vector meson photoproduction in the region of energies $1.7\le W\le 250GeV$ and photon virtualities $0 \le Q^2 \le 35 GeV^2$.
