Photoproduction of light mesons at SPring-8 LEPS2/BGOegg experiments

A photon beam with high linear polarization is available in the tagged energy range of 1.3¾2.4 GeV at the SPring-8 LEPS2 beamline. Large statistics data of hadron photoproduction have been collected at the LEPS2/BGOegg experiments by using a liquid hydrogen target, which is surrounded by a large acceptance electromagnetic calorimeter and charged particle detectors. The electromagnetic calorimeter consists of 1,320 BGO crystals, assembled in the "egg" shape covering the polar angle range of 24¾144 degrees. The reactions of γp ® π⁰p, γp ® ηp, and γp ® ωp have been analyzed in the meson decay modes of π⁰ / η ® γγ and ω ® π⁰γ. We measured the differential cross sections and photon beam asymmetries of these photoproduction processes to study baryon resonances. New experimental results will be shown, including the high energy region where the photon beam asymmetries had not been measured.
