dc.description.abstract | The reactions γp→ηp and γp→η′p are measured from their thresholds up to the center-of-mass energy W=1.96  GeV with the tagged-photon facilities at the Mainz Microtron, MAMI. Differential cross sections are obtained with unprecedented statistical accuracy, providing fine energy binning and full production-angle coverage. A strong cusp is observed in the total cross section for η photoproduction at the energies in the vicinity of the η′ threshold, W=1896  MeV (E<sub>γ</sub>=1447  MeV). Within the framework of a revised ηMAID isobar model, the cusp, in connection with a steep rise of the η′ total cross section from its threshold, can only be explained by a strong coupling of the poorly known N(1895)1/2<sup>−</sup> state to both ηp and η′p. Including the new high-accuracy results in the ηMAID fit to available η and η′ photo production data allows the determination of the N(1895)1/2<sup>−</sup> properties. | en_CA |
