Beam Asymmetries ($\mathrm{\Sigma }$) for ${\pi }^0$, $\eta$ and ${\eta }^{\mathrm{\prime }}$ 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 ($\mathrm{\Sigma }$) measurements using a tagged, linearly-polarized 9 GeV photon beam incident on a hydrogen target. Measurements of the beam asymmetry for the exclusive reactions $\gamma p\to {\pi }^{0}p$, $\gamma p \rightarrow \eta p$and$\gamma p \rightarrow \eta’ p$ will provide insight into the meson production mechanisms. GlueX measurements are the first beam asymmetry results for the $\eta$ and ${\eta }^{\mathrm{\prime }}$ 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 $\eta$ decay modes and the ${\eta }^{\mathrm{\prime }}\to {\pi }^{+}{\pi }^{-}\eta$ decay mode.
