Abstract

The beam polarization asymmetries for the p(γ, K+)λ and p(γ, K+)∑ 0 reactions were measured for the Eγ 1.5-2.4 GeV. The linearly polarized photons at the Laser-Electron-Photon facility at SPring-8 (LEPS) were used. It was found that the data were not consistent with theoretical predictions based on tree-level effective Lagrangian approaches.
