Abstract
Near-threshold J/ψ photoproduction plays a key role in the physics program at the Thomas Jefferson National Accelerator Facility (JLab) 12 GeV upgrade due to the wealth of information it has to offer. J/ψ photoproduction proceeds through the exchange of gluons in the t-channel and is expected to provide unique insight about the nucleon gluonic form factors and the nucleon mass radius. The JLab-based CLAS Collaboration, which uses the CEBAF Large Acceptance Spectrometer (CLAS12), aims to measure the near-threshold J/ψ photoproduction cross-section using both a proton and a deuteron target. The latter further offers the possibility of comparing the proton and neutron gluonic form factors and mass radii in a first measurement of the cross-sections off a proton or neutron within the deuteron target. These proceedings will describe the aims and experimental design for the measurement of near-threshold J/ψ photoproduction off the proton and neutron with the CLAS12 detector along with the current stage of the data analysis.
