Description
The GlueX experiment in Hall D, Jefferson Lab aims to map the meson spectrum, with a focus on exotic mesons and hybrids which are not allowed in a simple quark-antiquark model. In this talk, we present efforts to characterize the $\omega \pi^{0}$ decay channel of the $b_{1}(1235)$ meson as precursor to a search for the $\pi_{1}(1600)$ exotic hybrid meson candidate, which is predicted to decay dominantly to $b_{1} \pi$.
The cross-section of the $\omega \pi^{0}$ channel has been extracted as a function of photon beam energy and is of the order of 1 $\mu$b, in agreement with previous measurements. The differential cross section as a function of momentum transfer indicates the presence of two production processes based on a changing slope around 1 $GeV^{2}/c^{2}$. The analysis steps, corrections and systematic errors will be presented, along with preliminary amplitude analysis of the neutral and charged $\omega \pi$ final state.
