First Measurement of $a_{2}^{0} (1320)$ Polarized Photoproduction Cross Section

GlueX Collaboration, F. Afzal, C. S. Akondi +149

We measure for the first time the differential photoproduction cross section $d σ / d t$ of the $a_{2} (1320)$ meson at an average photon beam energy of 8.5~GeV, using data with an integr…

First Measurement of Near- and Sub-Threshold $J / ψ$ Photoproduction off Nuclei

J. R. Pybus, L. Ehinger, T. Kolar +65

We report on the first measurement of $J / ψ$ photoproduction from nuclei in the photon energy range of $7$ to $10.8$ GeV, extending above and below the photoproduction threshold in…

Measurement of Spin-Density Matrix Elements in $Δ^{++} (1232)$ photoproduction

F. Afzal, C. S. Akondi, M. Albrecht +146

We measure the spin-density matrix elements (SDMEs) of the $Δ^{++} (1232)$ in the photoproduction reaction $γ p \to π^{-} Δ^{++} (1232)$ with the GlueX experiment in Hall D at Jefferson…
