Measurement of the hard exclusive $π^{0}$ muoproduction cross section at COMPASS

G. D. Alexeev, M. G. Alexeev, C. Alice +169

A new and detailed measurement of the cross section for hard exclusive neutral-pion muoproduction on the proton was performed in a wide kinematic region, with the photon virtuality…

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…

Upper Limit on the Photoproduction Cross Section of the Spin-Exotic $π_{1} (1600)$

GlueX Collaboration, F. Afzal, C. S. Akondi +147

The spin-exotic hybrid meson $π_{1} (1600)$ is predicted to have a large decay rate to the $ω π π$ final state. Using 76.6~pb $^{- 1}$ of data collected with the GlueX detector, we meas…

First measurement using elliptically polarized photons of the double-polarization observable $E$ for $γ p \to p π^{0}$ and $γ p \to n π^{+}$

A2 Collaboration, F. Afzal, K. Spieker +74

We report the measurement of the helicity asymmetry $E$ for the $p π^{0}$ and $n π^{+}$ final states using, for the first time, an elliptically polarized photon beam in combination with…
