초록

We report the measurement of differential cross sections for omega and eta' photoproduction from protons at backward angles (-1.0 < cos Theta(X)(C. M) < -0.8) using linearly polarized photons at E-gamma = 1.5-3.0 GeV. The differential cross sections for omega mesons are larger than the predicted u-channel contribution based on amplitude analysis in the energy range 2.0 <= root s <= 2.4 GeV. The differential cross sections for omega and eta' mesons become closer to the predicted u-channel contribution at root s > 2.4 GeV. A bump structure in the root s dependence of the differential cross sections for eta' mesons was observed at root s similar to 2.35 GeV.
