The spin-exotic hybrid meson is predicted to have a large decay rate to the final state. Using 76.6~pb of data collected with the GlueX detector, we measure the cross sections for the reactions , , and in the range 8-10 GeV. Using isospin conservation, we set the first upper limits on the photoproduction cross sections of the and . We combine these limits with lattice calculations of decay widths and find that photoproduction of is the most sensitive two-body system to search for the .
