Book excerpt: We present a study of the reaction [gamma]p [right arrow] Xp [right arrow] KS0KS0p [right arrow] [pi]+[pi]−[pi]+[pi]−p using data collected by the GlueX Collaboration during the Spring 2017 run. The GlueX Experiment is housed in Hall D at the Thomas Jefferson National Accelerator Facility. A linearly polarized photon beam with a coherent peak at 9 GeV and maximum energy of 12 GeV is incident on a hydrogen target which is enclosed in a nearly hermetic detector capable of measuring the 4-momenta of charged and neutral particles. This experiment was designed to search for and measure the properties of light-quark hybrid mesons. A 90% pure sample of Ks0 was used to study resonances with 0++ and 2++ quantum numbers in the Ks0Ks0 invariant mass distribution. Three enhancements were observed in the Ks0Ks0 invariant mass distribution near 1.3 GeV, 1.5 GeV and 1.7 GeV. Four models with and without the f0(1710) as well as the f0(1500) or f'2(1525) were considered. Fits to the mass spectra give evidence at the 6[sigma] level in favor of the presence of the f0(1710) and slightly favor the f0(1500) over the f'2(1525). The differential cross section was measured as a function of -t with both the f0(1500)and f'2(1525). These measurements were compared to theoretical predictions and were found to be more consistent with the f'2(1525).
