摘要：
We report recent measurements of the gamma gamma ->eta eta process in the energy range, 1.096 GeV < W < 3.8 GeV and in scattering angle, broken vertical bar cos theta*broken vertical bar <= 0.9 or <= 1.0 depending on W, where W is the energy of the two -photon center-of-mass system and 0* is the eta scattering angle. In the lower energy region, we perform a partial wave analysis to the differential cross section and extract resonance parameters. In the higher energy region, (differential) cross section is compared with QCD predictions. We also present a study of eta(c) (2S) production with 6-prong final states in two -photon collisions.
