Searching for Hybrid Mesons in the Reaction γp−→ηη′p at GlueX
Presented by Jason Barlow, PhD, Assistant Professor of Physics

In this colloquium, Jason Barlow will discuss his work with the GlueX experiment in searching for “hybrid mesons.” These are particles that look very much like conventional mesons (quark and anti-quark pairs), but with a certain exception. The GlueX experiment is a fixed target experiment which uses a beam of linearly polarized photons incident on a hydrogen target. High precision detectors identify different types of particles. These particles are then traced back to a more specific reaction that happens near interaction of the photon beam with the hydrogen target. Certain software is used to reconstruct these interactions with data gathered from these detectors. Using properties of these particles, it can be determined if they are hybrid mesons. General features of the data will be shown with an emphasis on removing background reactions that contaminate the reaction of interest.
