Description
The quark model predicts a hierarchy of mesons with certain allowed $J^{PC}$, but experimental evidence has been found for several states with $J^{PC}$ that are forbidden for a pure quark anti-quark state. In the light quark sector, the most well studied of these states is the $\pi_1(1600)$. This state has several properties consistent with lattice QCD predictions for a light hybrid meson, a meson with an excited gluonic field. The GlueX experiment has collected high statistics photoproduction data, which will be used to study the properties of the $\pi_1(1600)$. This talk will summarize the current analysis efforts and future prospects for studying the $\pi_1(1600)$ at GlueX.
