Abstract: (arXiv)
A coherent study of the production of (, 2, 3 corresponding to , , and ) in is reported based on a previously proposed glueball and nonet mixing scheme, and a factorization for the decay of , where denotes the isoscalar vector mesons and , and denotes pseudoscalar mesons. The results show that the decays are very sensitive to the structure of those scalar mesons, and suggest a glueball in the GeV region, in line with Lattice QCD. The presence of significant glueball mixings in the scalar wavefunctions produces peculiar patterns in the branching ratios for , which are in good agreement with the recently published experimental data from the BES collaboration.- 13.25.Gv
