Title: Partial-wave analyses of γ p η p and γ n η n using a multichannel framework

Abstract

This paper introduces results from partial-wave analyses of the photoproduction reactions γp→ηp and γn→ηn. World data for the observables dσ/dΩ, Σ, T, P, F, and E were analyzed as part of this work. The dominant amplitude in the fitting range from threshold to a c.m. energy of 1900 MeV was found to be S 11 in both reactions, consistent with results of other groups. At c.m. energies above 1600 MeV, our solution deviates from published results, with this work finding higher-order partial waves becoming significant. Data off the proton imply that the higher-order terms contributing to the reaction include P 11, P 13, and F 15. The final results also hint that F 17 is needed to fit double-polarization observables above 1900 MeV. Data off the neutron show a contribution from P 13, as well as strong contributions from D 13 and D 15.
