Commissioning of the large-scale lead tungstate scintillating calorimeter
A. Somov, V. V. Berdnikov, L. Gan +4
This article reports on the installation and initial commissioning of a large-scale lead tungstate (PbWO4) scintillating crystal calorimeter developed for high-rate photon detectio…
Baryon-antibaryon photoproduction cross sections off the proton
GlueX Collaboration, F. Afzal, M. Albrecht +137
The GlueX experiment at Jefferson Lab has observed and, for the first time, and photoproduction from a proton target at photon energies up to 11.6 G…
Light Monitoring System for the Lead Tungstate Calorimeter in Hall D at Jefferson Lab
A. Somov, V. V. Berdnikov, H. Voskanyan +11
A new electromagnetic calorimeter composed of 1596 lead tungstate (PbWO) scintillating crystals has been constructed for the GlueX detector in Hall D at Jefferson Lab. The calo…
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…
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…
