Search for the $Y(2175)$ in the photoproduction cross section measurement of ${\hat{I}}^{3}p\to \ddot{I}•\ddot{I}{€}^{+}\ddot{I}{€}^{-}p$ at GlueX

GlueX Collaboration

Based on 334 pb${}^{-1}$ of photoproduction data collected with the GlueX detector at Jefferson Lab, we have measured for the first time the cross section of the exclusive reaction $…
