Beam Asymmetry of the $\eta^\prime$(958) meson through multiple decay channels in the GlueX Experiment
ORAL
Abstract
The $\eta$(548) and $\eta^\prime$(958) mesons are two of the richest unflavoured light mesons readily available at GlueX energies for studying meson resonances. Many other light mesons have decay channels involving the $\eta$ mesons with significant branching ratios, and $\pi\eta$/$\pi\eta^\prime$ resonances are among the top contenders for possibly-accessible exotic and hybrid resonances which GlueX aims to study. As such, the ability to reconstruct pure $\eta$/$\eta^\prime$ samples and analyze their decays is of utmost importance for understanding future work on more complicated decay structures. One of the first observables we can measure is the $\Sigma$ beam asymmetry, which for the $\eta^\prime$ has never been measured at beam energies above a few GeV. In this talk, preliminary analysis results for the $\eta^\prime$ beam asymmetry will be presented.
