Photoproduction of the $b_{1}(1235)$ meson in GlueX

The GlueX detector is essentially hermetic, thus allowing reconstruction of all final state particles from photoproduction off a liquid hydrogen target at 9 GeV. In this talk we discuss the channel $\gamma p \rightarrow p \pi^{+} \pi^{-} 4 \gamma$ with focus on the reaction $\gamma p \rightarrow p b_{1}(1235)$, where the axial-vector meson $b_{1}(1235)$ decays to $\omega \pi$.This investigation will commence by inspecting the invariant mass spectra and Dalitz plots as a function of the Mandelstam variable $-t$, to investigate the production mechanism of the $b_1$ and serve as the first step in investigating the decays of heavier mesons to $\omega\pi^0$.
