The GlueX experiment at Jefferson Lab aims to study the light meson spectrum with an emphasis on the search for hybrid exotic mesons. A tagged photon beam, with energies in the range 3—11.6 GeV, and linearly polarized near 8.5 GeV, is incident on a hydrogen target inside a detector with near-complete neutral and charged particle coverage. The experiment has completed its first phase of data...
The GlueX experiment studies the light meson spectrum and searches for hybrid and exotic mesons. As part of its program, photoproduction cross sections of $\eta$ mesons have been measured in the $\gamma + p \rightarrow \eta + p$ reaction in a new, previously unexplored kinematic regime at beam energies up to 11 GeV, and production polar angles down to 8$^\circ$. The new cross section results...
With a need to understand the physics attributed to the light-quark meson spectrum, multiple past experiments have searched into the possibility of non quark-antiquark (exotic) quantum numbers. The search for exotic hybrid mesons at the GlueX experiment has advanced past previous experiments' data collection with the initial phase of data accumulation being completed during 2018; higher...
The GlueX experiment in Hall D, Jefferson Lab aims to map the meson spectrum, with a focus on exotic mesons and hybrids which are not allowed in a simple quark-antiquark model. In this talk, we present efforts to characterize the $\omega \pi^{0}$ decay channel of the $b_{1}(1235)$ meson as precursor to a search for the $\pi_{1}(1600)$ exotic hybrid meson candidate, which is predicted to decay...
A proposal for a secondary beam of neutral kaons in Hall D at Jefferson Lab was recently approved by the JLab PAC. The experiment will use the GlueX experimental setup to study hyperon spectroscopy by measuring both the differential cross sections and self-analyzed polarizations of the produced $\Lambda$, $\Sigma$, $\Xi$, and $\Omega$ hyperons using the GlueX detector at the Jefferson Lab...
