Moments of angular distribution and beam asymmetries in $\eta {\pi }^0$ photoproduction at GlueX

V. Mathieu, M. Albaladejo, C. Fernández-Ramírez +4

In the search for exotic mesons, the GlueX collaboration will soon extract moments of the $\eta {\pi }^0$ angular distribution. In the perspective of these results, we generalize the formal…
