Near-Threshold J/ $I ¨ \to I^¼^{+} I^¼^{-}$ Photoproduction and the Gluonic Gravitational Form Factors of the Proton

007 Collaboration, S. Joosten, Z. -E. Meziani +56

We report on the measurement of the two-dimensional differential cross section for near-threshold J/ $I ¨ \to I^¼^{+} I^¼^{-}$ photoproduction from the J/ $I ¨ $ -007 experiment in Hall C at Jef…

Measurement of the Total Compton Scattering Cross Section between 6.5 and 11 GeV

GlueX Collaboration, F. Afzal, C. S. Akondi +148

The total cross section for Compton scattering off atomic electrons, $Î³+e\rightarrowÎ³'+e'$, was measured using photons with energies between 6.5 and 11.1 GeV incident on a $^{9}$ Be…

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

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

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

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 $d I ¨ / d t$ of the $a_{2} (1320)$ meson at an average photon beam energy of 8.5~GeV, using data with an integ…

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

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

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

Pion electroproduction measurements in the nucleon resonance region

R. Li, N. Sparveris, H. Atac +46

We report new pion electroproduction measurements in the $I^ (1232)$ resonance, utilizing the SHMS - HMS magnetic spectrometers of Hall C at Jefferson Lab. The data focus on a regio…
