Photoproduction on nuclear targets (A > 1) at multi-GeV energies is being considered as an interesting future application of the GlueX detector beyond the meson spectroscopy program. The aim of the workshop is to explore the physics potential of nuclear photoproduction with GlueX, including theoretical motivation, experimental methods, equipment needs, and wider context of such measurements. Unique capabilities that GlueX would bring to photoproduction physics are linear photon polarization, excellent energy resolution through tagging, and wide energy coverage from ~5 GeV to 12 GeV. Physics topics include:
- Medium modification of light vector mesons (rho, omega, phi)
- J/psi as a probe of nuclear color fields
- Coherent nuclear processes, including Primakoff production
- Polarization observables in nuclear photoproduction
A Letter of Intent for nuclear photoproduction with GlueX was favorably reviewed by JLab's PAC43 in 2015. The workshop aims to solicit the advice of world experts and stimulate further development, in order to initiate preparation of a full proposal to PAC44 in 2016.
The workshop is part of a broader effort by the GlueX collaboration and Jefferson Lab to explore new physics applications of the GlueX detector beyond the meson spectroscopy program. An initial assessment of the physics potential of nuclear photoproduction with GlueX was made at the 2008 Workshop "Photon-hadron physics with the GlueX detector at Jefferson Lab".
