The quarkonia-glueball structure of η, η' and η(1410) revisited

The quarkonia-glueball structure of η, η' and η(1440) is phenomenologically deduced from the updated world average data including two-photon decays of pseudoscalar mesons, radiative decays between pseudoscalar and vector mesons, decays of J/ψ into a vector and a pseudoscalar meson, and radiative decays of J/ψ. Corrections due to SU(3) flavor symmetry breaking, non-ideal ω-φ mixing, double OZI and electromagnetic amplitudes of J/ψ decays into a vector and a pseudoscalar meson, and three-gluon-annihilation amplitudes of radiative decays of J/ψ are included in our analysis. Some predictions on the decays involving η(1410) are presented, which can be tested at Beijing Electron Positron Collider/Beijing Spectrometer (BEPC/BES) with 50 million J/ψ events. (orig.)
