Resonances in the ωη System at GlueX

ORAL

Abstract

The GlueX experiment has produced the world's largest data sample for peripheral photoproduction of mesons with a goal to unambiguously identify new and exotic mesons. In this talk, we will presents the current status of the search for possible intermediate resonances which decay to ωη, such as the known ω(1650), exotics with JPC=0--,2+-, and elusive ones with JPC=2--. The ω, in this reaction, is identified via the π+ π- π0 decay mode and the η and π0 are identified via the decay to 2γ. The data set was obtained at the Thomas Jefferson National Accelerator Facility utilizing the GlueX detector and a tagged linearly polarized photon beam that peaks between 8 - 9 GeV incident on a liquid hydrogen target. With over 100k events, an initial amplitude analysis of the data will be presented along with plans for future studies.
