Measurement of t-dependence of the Beam Asymmetry for a reaction $\gamma$ p $\rightarrow$ $\eta'$ p at GlueX

The GlueX experiment is a photoproduction experiment located at Thomas Jefferson National Laboratory in Newport News, Virginia. We report on the measurements of the Beam Asymmetry ($\Sigma$) for a reaction $\gamma p\rightarrow \eta' p$, using a tagged, linearly polarized 9 GeV photon beam incident on a liquid hydrogen target. A previous measurement utilizing 17$\%$ of the GlueX Phase-1 data set, which was limited to momentum transfer up to $-$t$=$0.95 (GeV/c)$^2$, indicated that the reaction mechanism is dominated by $\rho$ and $\omega$ meson exchanges[1].The current analysis uses full GlueX Phase-1 data. This allows us to study whether the $\rho$ and $\omega$ exchanges dominance holds true at higher momentum transfer($-$t). We will present the latest results on azimuthal angular distributions, yield asymmetries and beam asymmetries as a function of $-$t for different $\eta'$ decay modes which are $\eta'$ $ \rightarrow$ $\eta$$\pi^{+}$$\pi^{-}$ and $\eta'$ $\rightarrow$ $\eta$ $\pi^{0}\pi^{0}$ with newly obtained upper limit in $-t$ from current analysis.
