Love, W A

The current favorite candidate theory of strong interactions is Quantum Chromodynamics. In this theory, bound states of two or more gluons, called glueballs, must exist. Experimentally, the detection of glueballs (all of which are massive enough to decay quickly to ordinary q anti q hadrons) is complicated by the lack of any explicit signature. The calculation of the mass of the low-lying glueballs by lattice gauge methods and the MIT bag model at present give only a rough guide to experimental searches. A popular place to look has been among the systems recoiling from photons emitted in heavy quarkonium decays. In general, processes which must exchange hard gluons are needed. One touchstone seems to be the concept of democracy. Unmixed glueball states are flavor singlets and should show equal decay amplitudes to states made of strange or non-strange quarks (or indeed of charmed or b quarks at higher masses). The MPS Experiment number 679 setup and results are described.
