Study of η and η' Photoproduction:. from Threshold to High Energies

A reggeized model for η and η' photoproduction on the nucleon is presented. In this model, t-channel vector meson exchanges are described in terms of Regge trajectories to comply with the correct high energy behavior. We compare this reggeized model with an isobar model (η-MAID), where the t-channel exchanges are described by ρ and ω poles. Both models describe current γp → ηp data up to E_{γ }^{lab} = 2 {GeV} quite well, but only the reggeized model can be successfully extended to higher energies. For the γp → η'p reaction, only the reggeized model is able to give a satisfactory description.
