摘要：
We present differential cross sections and photon beam asymmetries of photoproduction reactions of eta mesons in the center-of-mass energy of 1.82 < W < 2.32 measured in LEPS2/BGOegg experiment. The differential cross section at cos theta(eta)(c.m.) < -0.6 shows a bump structure at W similar to 2.2 GeV, suggesting the appearance of the baryon resonances with hidden ss<($)over bar>. The photon beam asymmetries at W > 2.1 GeV were measured for the first time.
