Abstract: (Physical Society of Japan)

New high-precision total and differential cross sections for η and η′ photoproduction on the proton obtained by the A2 Collaboration at the Mainz Microtron are presented. The data for η photoproduction demonstrate a cusp at the energy W ∼ 1.9 GeV. Furthermore, we present a new version of the ηMAID model for η and η′ photoproduction. The model includes 23 nucleon resonances parametrized with Breit–Wigner shapes. The background is described by vector and axial-vector meson exchanges in the t channel using the Regge phenomenology. Parameters of the resonances were obtained from a fit to preliminary data of the A2 Collaboration at MAMI and available data from other collaborations. The cusp is explained as a threshold effect due to the opening η′p decay channel of the N(1895)1/2^− resonance.
