The GlueX collaboration will soon extract moments of the eta-pi0 angular distribution. In the perspective of these results, we built a model for the photoproduction of eta-pi0 with a linearly polarized beam to illustrate the influence of the P-wave in unpolarized and polarized moments. We also generalize the definition of the beam asymmetry for two mesons photoproduction and show that, when the meson momenta are perpendicular to the reaction plane, the beam asymmetry can distinguish even and odd waves. We illustrate this beam asymmetry with our model and show how it can be used to identify the presence of an exotic P wave.</div><div class=""><br class=""></div><div class="">Thank you.</div><p style="margin-top: 0px; margin-bottom: 0px;" class=""></p></font></div></pre><pre cols="72" style="white-space: pre-wrap;" class=""><font face="Helvetica" style="font-size: 14px;" class="">Carlota, Vincent & Raza</font></pre><div class=""><br class=""></div></div></body></html>
