Pseudoscalar-glueball production in psi to gamma X, Upsilon to gamma X, e/sup +/e/sup -/ to e/sup +/e/sup -/X, and pp to X
Saturation of the observed rate and spectrum of psi to gamma +hadrons by a 2-GeV 0/sup -/ 'glueball' G, and the use of SU(3)*SU(3) Ward identities (incorporating the U(1) axial anomaly) implies the possibility of a substantial cross section ( approximately 0.5 nb) for the process ee to eeG...
