Unified treatment of electroproduction for all vector mesons Original Research Article

We present results of a treatment for elastic photo- and electroproduction of ρ, ω, ϕ, J/ψ and ϒ vector mesons based on a framework in which the photon and vector meson wave functions and properties of the QCD vacuum field play prominent roles. The model, which has been applied and tested before, is used, without free parameters, in a successful description of the existing data and for predictions in extended kinematical ranges.
