Measurement of t-Dependence of the Beam Asymmetry using a reaction $\gamma$ p $\rightarrow$ $\eta'$ p off the Proton at GlueX

The GlueX experiment is a photoproduction experiment which is located at Thomas Jefferson National Lab in Newport News, Virginia. We report on measurements of the beam asymmetry ($\Sigma$) in the reaction $\gamma p\rightarrow \eta' p$, using a tagged, linearly polarized 9 GeV photon beam incident on a liquid hydrogen target. A previous measurement, which was limited to momentum transfer up to $-t=0.9 $ (GeV/c)$^2$, indicated that the reaction mechanism is dominated by $\rho$ and $\omega$ meson exchanges [1]. Use of higher statistics will allow us to study whether this holds true at higher momentum transfer. We will present the preliminary results from ongoing analysis in particular azimuthal angular distributions, yield asymmetries and extracted beam asymmetries as a function of $-t$ for different $\eta'$ decay modes such as $\eta'$ $ \rightarrow$ $\eta$$\pi^{0}$$\pi^{0}$ \ \ and \ \ $\eta'$ $\rightarrow$ $\eta$ $\pi^{+}\pi^{-}$.
