Description

The GlueX experiment has produced the world's largest data sample for peripheral photoproduction of mesons with a goal to expand our understanding of the strong interaction and search for hybrid mesons. The experiment at the Thomas Jefferson National Accelerator Facility utilizes the GlueX detector and a tagged linearly polarized photon beam that peaks between 8 - 9 GeV incident on a liquid hydrogen target. Multiple partial-wave analyses are ongoing in the collaboration, and some exhibit ambiguous behavior in their result. We will present the mathematical nature of these ambiguities and tools to help diagnose if either the model or data will exhibit these ambiguities. Lastly, we will introduce tentative solutions to help address these obstacles.
