Title Measurement of the Beam Asymmetry for the ETA and ETA Prime Mesons with the GlueX Experiment
Abstract The GlueX Experiment in Hall D at Jefferson Lab ultimately aims to provide evidence of hybrid mesons, quark-antiquark pairs with gluonic excitations, which are predicted by quantum chromodynamics calculations on the lattice. GlueX features a linearly-polarized photon beam incident on a liquid hydrogen target and a nearly-four-pi hermetic detector capable of measuring positions and momenta of both charged and neutral final state particles generated in the target. The short-term physics goals of GlueX are to measure observables and properties of the known particles, especially those that are likely decay products of hybrids, such as the eta and eta-prime mesons. An overview of the detector subsystems and the long-term physics goals of GlueX are presented, along with analyses on the Sigma beam asymmetry of the eta and eta-prime mesons. The measurements of Sigma are presented versus the four-momentum transfer squared using a photon beam energy of 8.2-8.8 GeV in the three main decay channel
