Comprehensive Measurement of *h' Photoproduction off the Proton at E*g<2.4 GeV / N.Muramatsu, E.A.Strokovsky, [a.o.]. – Text : electronic // Physical Review C. – 2026. – Vol. 113, No. 6. – P. L062201. – URL: https://doi.org/10.1103/s7m3-8xjq.

For the spectroscopy of nucleon resonances at the total energies from the 𝜂′-meson production threshold to 2.32 GeV, photon beam asymmetries of the reaction 𝛾⁢𝑝→𝜂′⁢𝑝 were measured together with total and differential cross sections by analyzing the two decay modes 𝜂′→𝛾⁢𝛾 and 𝜋0⁢𝜋0⁢𝜂. New constraints for amplitude decomposition were given by the first-time result of photon beam asymmetries at 𝐸𝛾>1.84 GeV and the most precise data of differential cross sections to date at extremely backward 𝜂′ angles. The possibility of a larger coupling constant of the 𝜂′-nucleon system to the 𝑁⁡(2250) resonance was implied in the partial wave analyses using the present data.
