摘　　要：By studying theηc exclusive decay to double glueballs,we introduce a model to phenomenologically mimic the gluon-pair-vacuum interaction vertices,namely the 0^++model.Based on this model,we study glueball production in pseudoscalar quarkonium decays,explicitlyηc→f0(1500)η(1405),ηb→f0(1500)η(1405),andηb→f0(1710)η(1405)processes.Among them f0(1500)and f0(1710)are well-known scalars possessing large glue components,whileη(1405)is a potential candidate for a pseudoscalar glueball.The preliminary calculation results indicate that these processes are marginally accessible in the presently running experiments BES III,BELLE II,and LHCb.
