Search for Glueballs from Three-body Annihilation of Antiproton-Proton in-Flight

Abstract

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.
