Measurement of beam asymmetry for ${\pi }^{-}{\Delta }^{++}$ photoproduction on the proton at $E_{\gamma }$=8.5 GeV

GlueX Collaboration, S. Adhikari, C. S. Akondi +134

We report a measurement of the ${\pi }^{-}$ photoproduction beam asymmetry for the reaction $\vec{\gamma }p\to {\pi }^{-}{\Delta }^{++}$ using data from the GlueX experiment in the photon beam energy…
