  Lattice QCD and other theoretical models predict that the 0(-+), 2(++) and
2(-+) glueballs have masses in the range of 2.0 to 2.4 GeV. For resonances in
such an energy range, three-body decay modes are expected to be large. The
strategy for looking for these glueballs and the newest results from studying
Crystal Barrel data on the three-body annihilation of proton-antiproton in
flight are presented.
