Amplitude Analysis of a₂→ηπ at GlueX

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 ηπ 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, γp→ηπ ⁰p, and charged, γp→ηπ^-Δ⁺⁺, processes. This presentation will discuss the amplitude analysis of a₂→ηπ channels at GlueX. It will focus on and compare the extraction of differential cross sections for the photoproduction of a₂→ηπ as a function of t for the neutral and charged ηπ systems. This work is the first step towards studying the production of the hybrid π₁(1600) in η(')π channels at GlueX.
