Title: {eta}{sup '} Photoproduction on the Proton for Photon Energies from 1.527 to 2.227 GeV

Abstract

Differential cross sections for the reaction {gamma}p{yields}{eta}{sup '}p have been measured with the CLAS spectrometer and a tagged photon beam with energies from 1.527 to 2.227 GeV. The results reported here possess much greater accuracy than previous measurements. Analyses of these data suggest for the first time the coupling of the {eta}{sup '}N channel to both the S{sub 11}(1535) and P{sub 11}(1710) resonances, known to couple strongly to the {eta}N channel in photoproduction on the proton, and the importance of J=3/2 resonances in the process.
