First Measurement of $a^0_2(1320)$ Polarized Photoproduction Cross Section

GlueX Collaboration, F. Afzal, C. S. Akondi, M. Albrecht et autres

We measure for the first time the differential photoproduction cross section $dσ/dt$ of the $a_2(1320)$ meson at an average photon beam energy of 8.5~GeV, using data with an integrated luminosity of 104~pb$^{-1}$ collected by the GlueX experiment. We fully reconstruct the $γp …

Upper Limit on the Photoproduction Cross Section of the Spin-Exotic π 1 ( 1600 )

F. Afzal, C. S. Akondi, M. Albrecht, M. J. Amaryan et autres

The spin-exotic hybrid meson ${\ensuremath{\pi}}_{1}(1600)$ is predicted to have a large decay rate to the $\ensuremath{\omega}\ensuremath{\pi}\ensuremath{\pi}$ final state. Using $76.6\text{ }\text{ }{\mathrm{pb}}^{\ensuremath{-}1}$ of data collected with the GlueX detector, we measure the cross sections for the reactions $\ensuremath{\gamma}p\ensuremath{\rightarrow}\ensuremath{\omega}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}p$, $\ensuremath{\gamma}p\ensuremath{\rightarrow}\ensuremath{\omega}{\ensuremath{\pi}}^{0}{\ensuremath{\pi}}^{0}p$, and $\ensuremath{\gamma}p\ensuremath{\rightarrow}\ensuremath{\omega}{\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\pi}}^{0}{\mathrm{\ensuremath{\Delta}}}^{++}$ in …
