Resonance η′-meson photoproduction on protons at photon energies from the reaction threshold to 3700 MeV

摘要

The parameters of six resonances of the isobar model for η′-meson photoproduction were fitted to experimental differential cross sections for the reaction γπ → η′p that weremeasured by the CLAS-2009 and CBELSA/TAPS Collaborations (Mainz, Germany). It was shown that, in the photon energy region from the reaction threshold to 3700MeV, a good description of the experimental cross sections was attained by taking into account the contributions of high-angular-momenta heavy resonances alone.
