Description
The primary goal of the GlueX experiment at Jefferson Lab is to search for and map the spectrum of light hybrid mesons. Many experiments have studied and reported evidence of exotic mesons decaying into $\eta\pi$ and $\eta'\pi$ final states. GlueX, which has a linearly polarized photon beam and a large acceptance for both charged and neutral particles, has access to both the neutral, $\gamma p\to\eta\pi^{0}p$, and charged, $\gamma p\to\eta\pi^{-}\Delta^{++}$, processes. This presentation will discuss the amplitude analysis of $a_2\to\eta\pi$ channels at GlueX. It will focus on and compare the extraction of differrential cross sections for $a_{2}\to\eta\pi$ as a function of $t$ for both the neutral and charged processes. This work is the first step towards studying the production of the hybrid $\pi_{1}(1600)$ in $\eta(')\pi$ channels at GlueX.
