Background study and preliminary amplitude analysis results for $\gamma p \rightarrow \eta^{\prime} \pi^0p$ at GlueX

The GlueX experiment at Hall-D in Jefferson Lab uses a tagged photon beam with linear polarization peaking around 9 GeV on a liquid hydrogen target to study the spectrum of conventional mesons and search for hybrid exotic mesons. The spectrometer is designed to have an almost 4$\pi$ acceptance and good efficiency especially suited to study multi-particle final states in both charged and neutral modes. This talk will report on the analysis of $\gamma p \rightarrow \eta^{\prime} \pi^0p$ focusing on the background systematics underneath the $\eta^{\prime}$ signal and preliminary results from amplitude analysis of the $\eta^{\prime} \pi^0$ invariant mass spectrum.
