Beam Asymmetries ($Σ$) for $π^0$, $η$ and $η'$ in Photoproduction at GlueX
The GlueX experiment is a photoproduction experiment located at Thomas Jefferson National Lab in Newport News, Virginia. GlueX is capable of making beam asymmetry ($Σ$) measurements using a tagged, linearly-polarized 9 GeV photon beam incident on a hydrogen target. Measurements of the beam asymmetry for the exclusive reactions $γp \rightarrow π^0 p$, $γp \rightarrow ηp$ and $γp \rightarrow η' p$ will provide insight into the meson production mechanisms. GlueX measurements are the first beam asymmetry results for the $η$ and $η'$ in this energy range and are expected to further constrain Regge theory models for photoproduced pseudoscalar mesons. This talk will present preliminary results of the photon beam asymmetries as a function of the Mandelstam variable, t, for multiple $η$ decay modes and the $η'\rightarrowπ^+π^-η$ decay mode.
