Abstract

A study of the partial-wave content of the γp→η^′p reaction in the fourth resonance region is presented, which has been prompted by new measurements of polarization observables for that process. Using the Bonn–Gatchina partial-wave formalism, the incorporation of new data indicates that the N(1895)1/2⁻, N(1900)3/2⁺, N(2100)1/2⁺, and N(2120)3/2⁻ are the most significant contributors to the photoproduction process. New results for the branching ratios of the decays of these more prominent resonances to Nη^′ final states are provided; such branches have not been indicated in the most recent edition of the Review of Particle Properties. Based on the analysis performed here, predictions for the helicity asymmetry E for the γp→η^′p reaction are presented.
