Description
The GlueX experiment in Hall D at Jefferson Lab studies the spectrum of light hadrons in photoproduction with a high-energy, linearly polarized photon beam. A central goal is the search for new states in the hadron spectrum, including states with gluonic degrees of freedom, pursued in both the non-strange sector, through manifestly exotic quantum numbers, and the strange sector, as supernumerary states in the excited strange-meson spectrum. Recent results along the path toward this goal will be presented in three parts: spectroscopy of exclusive final states with partial-wave analysis, spin dynamics of the production mechanism from spin-density matrix elements and recoil-hyperon polarization, and near-threshold J/ψ and baryon–antibaryon photoproduction as probes of gluonic structure and hadronization. In addition, prospects for future measurements from existing data and the upcoming, high-intensity GlueX-III charmonium program will be discussed.
