Measurement of the beam asymmetry $\Sigma$ for ${\pi }^0$ and $\eta$ photoproduction on the proton at $E_{\gamma }=9$ GeV

GlueX Collaboration, H. Al Ghoul, E. G. Anassontzis +123

We report measurements of the photon beam asymmetry $\Sigma$ for the reactions $\vec{\gamma }p\to p{\pi }^0$ and $\vec{\gamma }p\to p\eta$ from the GlueX experiment using a 9 GeV linearly-polarized, tagged pho…
