Photoproduction of eta-prime-mesons from the Proton

The presently available data for the reaction $γp{\to}η^\prime{p}$ are analyzed in terms of a model in which the dominant production mechanism is the exchange of the vector mesons $ω$ and $ρ$. To describe the data at photon energies close to the production threshold we introduce a resonance contribution due to the well established $S_{11}(1535)$ resonance. Finally we study the contributions due to nucleon exchange to the $η^\prime$ photoproduction and find, that those contributions can be seen at large angles in the differential cross section.
