Amplitude Analysis of ωπ⁰Photoproduction at GlueX

The GlueX experiment at Jefferson Laboratory seeks to map out the spectrum of light mesons produced from a linearly polarized photon beam. The production and decays of a light meson resonance X such as γp→ Xp' →ωπ⁰p' can be modeled with polarized vector-pseudoscalar amplitudes, which can describe the contribution of individual amplitudes to the total measured intensity. The status of mass-independent fits to the ωπ⁰ mass spectrum over a wide range of mass and momentum transfer -t will be presented, with an emphasis on interactions with the b₁(1235) meson. We will also present in parallel an analysis of moments of the angular distributions for the same process, as a means of verifying the stability of the amplitude-based results. These results will help to improve the broader knowledge of light meson states and how they are produced.
