Abstract

The beam polarization asymmetries for the p(γ^→, K⁺)λ and p(γ^→, K⁺)∑ ⁰ reactions were measured for the E_γ 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.
