Abstract.
The isobar model EtaMAID has been updated with new and high precision data for \(\eta\) and \(\eta^{\prime}\) photoproduction on protons and neutrons from MAMI, ELSA, GRAAL and CLAS. The background is described in a recently developed Regge cut model, and for the resonance part the whole list of nucleon resonances has been investigated with 21 \(N^{\ast}\) states contributing to \(\eta\) photoproduction and 12 \(N^{\ast}\) states contributing to \( \eta^\prime\) photoproduction. A new approach is discussed to avoid double counting in the overlap region of Regge and resonances. A comparison is done among four newly updated partial waves analyses for observables and partial waves. Finally, the possibility of a narrow resonance near \(W = 1900\) MeV is discussed, that would be able to explain unexpected energy and angular dependence of observables in \( p(\gamma,\eta^{\prime})p\) near \(\eta^{\prime}\) threshold.
