Abstract

We report the measurement of differential cross sections for ω and η ' photoproduction from protons at backward angles -1.0< cos ΘC.MX< -0.8) using linearly polarized photons at Eγ =1.5-3.0GeV. The differential cross sections for ω mesons are larger than the predicted u-channel contribution based on amplitude analysis in the energy range 2.0≤ √s≤ 2.4GeV. The differential cross sections for ω and η ' mesons become closer to the predicted u-channel contribution at √ s>2.4GeV. A bump structure in the √ s dependence of the differential cross sections for η ' mesons was observed at √ s∼2.35GeV.
