Measurement of the Beam Asymmetry Σ for Π⁰ and η Photoproduction on the Proton at Eγ=9 GeV
We report measurements of the photon beam asymmetry Σ for the reactions γ - p→pπ0 and γ - p→pη from the GlueX experiment using a 9 GeV linearly polarized, tagged photon beam incident on a liquid hydrogen target in Jefferson Lab's Hall D. The asymmetries, measured as a function of the proton mom...
