Threshold Photoproduction as a Probe of Nuclear Gluon Structure
J. R. Pybus, D. Dutta, H. Gao +83
The nuclear EMC effect is the observation that quark distributions in bound nucleons experience significant modification at large relative to free nucleons. Despite decades of…
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, $γ+e\rightarrowγ'+e'$, was measured using photons with energies between 6.5 and 11.1 GeV incident on a Be…
Upper Limit on the Photoproduction Cross Section of the Spin-Exotic
GlueX Collaboration, F. Afzal, C. S. Akondi +147
The spin-exotic hybrid meson is predicted to have a large decay rate to the final state. Using 76.6~pb of data collected with the GlueX detector, we…
First Measurement of Polarized Photoproduction Cross Section
GlueX Collaboration, F. Afzal, C. S. Akondi +149
We measure for the first time the differential photoproduction cross section of the meson at an average photon beam energy of 8.5~GeV, using data with an integ…
First Measurement of Near- and Sub-Threshold Photoproduction off Nuclei
J. R. Pybus, L. Ehinger, T. Kolar +65
We report on the first measurement of photoproduction from nuclei in the photon energy range of to GeV, extending above and below the photoproduction threshold in…
Measurement of Spin-Density Matrix Elements in photoproduction
F. Afzal, C. S. Akondi, M. Albrecht +146
We measure the spin-density matrix elements (SDMEs) of the in the photoproduction reaction with the GlueX experiment in Hall D at Jeffer…
