Title: η′ meson photoproduction off nucleon in the isobar model

Abstract

The recent high-precision data for the reaction γ p → pη′ at center-of-mass energies from near threshold up to 2.84 GeV is obtained by the CLAS collaboration at the Jefferson Laboratory [1] have been analyzed within an isobar model. The η′ photoproduction can be described quite well over the entire energy range of available data by considering S {sub 11} and P{sub 11} resonances, in addition to the nucleon s- and u-channel resonance contribution, also t-channel mesonic currents. For the resonances considered, our analysis we use masses and widths advocated by the Particle Data Group. We emphasize, that cross-section data alone are able to reproduce the value of resonance parameters and hadronic coupling constant.
