The GlueX experiment at Jefferson Lab studies photoproduction of mesons using linearly polarized $8.5\phantom{\rule{4pt}{0ex}}\text{GeV}$ photons impinging on a hydrogen target which is contained within a detector with near-complete coverage for charged and neutral particles. We present measurements of spin-density matrix elements for …

New results from the GlueX experiment provide improved cross sections for the photoproduction from the proton of $J/\ensuremath{\psi}$ mesons via the $\ensuremath{\gamma}+p\ensuremath{\rightarrow}J/\ensuremath{\psi}+p$ reaction. Such mesons have charm/anti-charm heavy-quark content. Measurements of this reaction near the kinematic threshold can help constrain aspects of …

We report the total and differential cross sections for $J/ψ$ photoproduction with the large acceptance GlueX spectrometer for photon beam energies from the threshold at 8.2~GeV up to 11.44~GeV and over the full kinematic range of momentum transfer squared, $t$. Such coverage …
