Photoproduction of vector mesons in the soft dipole Pomeron model

Exclusive photoproduction of all vector mesons by real and virtual photons is considered in the soft dipole Pomeron model. It is emphasized that, the Pomeron in this model being a double Regge pole with an intercept equal to 1, we are led to rising cross sections but the unitarity bounds are not violated. It is shown that all available data for rho,omega,Phi,J/psi, and Y in the region of energies 1.7less than or equal toWless than or equal to250 GeV and photon virtualities 0less than or equal toQ(2)less than or equal to35 GeV2, including the differential cross sections in the region of transfer momenta 0less than or equal to\t\less than or equal to1.6 GeV2, are well described by the model.
