Production and decay processes involving pseudoscalar gluonium particles

Production and decay processes involving eta, eta', and i(1440) mesons are considered in order to elucidate the quark content of these mesons and also to obtain information about the quark-gluon mixing in them. Predictions are made for a large number of two-particle decays involving eta, eta', and i(1440)-- pseudoscalar gluonium particles, together with predictions of the differential cross sections for production of these gluonium particles in reactions with hypercharge exchange
