η and η' photoproduction with EtaMAID including Regge phenomenology

الأصل · EN

We present a new version of the EtaMAID model for η and η' photoproduction on nucleons. The model includes 23 nucleon resonances parameterized with Breit-Wigner shapes. The background is described by vector and axial-vector meson exchanges in the t channel using the Regge cut phenomenology. Parameters of the resonances were obtained from a fit to available experimental data for η and η' photoproduction on protons and neutrons. The nature of the most interesting observations in the data is discussed.
