Description
We investigate the $\pi^0\eta$ photoproduction off protons using a 4π electromagnetic calorimeter BGOegg at Spring-8 BL31LEP with a linearly polarized photon beam produced via laser Compton scattering in the energy region of 1.3−2.4 GeV. The conventional beam asymmetry $\Sigma$ is obtained with the quasi-two-body approach, while $I^c$ and $I^s$ are deduced via exploiting the full three-body kinematics which characterize the spin-alignment of the intermediate state when absorbing a linearly polarized photon. These polarized observables, especially $I^c$ and $I^s$ are important for studying the dynamics of the intermediate resonance.
