GLUEBALL PRODUCTION IN HIGH-ENERGY COLLISIONS

Using a nonrelativistic gluon bound-state model, we compute the subprocesses qg --> qG, qqBAR --> gG, gg --> gG, and their contribution to the overall reaction ppBAR --> jet + glueball + X, assuming that the glueball G and the quark (gluon) jet are emitted with their transverse momenta large (> 10 GeV), opposite, and approximately equal. We show that, for present glueball candidates and for their possible quantum states, fairly large predictions are obtained, thus justifying future experiments of this type that might be performed at high-energy ppBAR or pp colliders, such as the CERN SppBARS or the Fermilab Tevatron.
