Description
The GlueX Experiment uses an intense photon beam of with energies up to 12 GeV and a large acceptance spectrometer to study many issues in hadron physics. These characteristics allow in particular for the study of comparatively rare photoproduction processes. The study of doubly strange baryons is particularly interesting for understanding the baryon spectrum, due to many states which are poorly known or unidentified that are expected to be narrow. The GlueX data has allowed for the identification of several of these states, opening a new window to the study of the cascade baryon spectrum. Additionally, the photoproduction of charmonium states near threshold is expected to proceed dominantly through the exchange of gluons with a target nucleus, therefore providing information on the gluonic structure of the nucleon. GlueX has collected the world's largest sample of photoproduced J/psi near threshold, and has identified higher excited charmonium states such as the chi_cJ(1P) and psi(2S) states in photoproduction.
The status and prospects of both of these efforts will be reviewed.
