Abstract.
The quarkonia-glueball structure of \(\eta\), \(\eta^{'}\) and \(\eta(1440)\) 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 \(J/\psi\) into a vector and a pseudoscalar meson, and radiative decays of \(J/\psi\). Corrections due to SU(3) flavor symmetry breaking, non-ideal \(\omega\)-\(\phi\) mixing, double OZI and electromagnetic amplitudes of \(J/\psi\) decays into a vector and a pseudoscalar meson, and three-gluon-annihilation amplitudes of radiative decays of \(J/\psi\) are included in our analysis. Some predictions on the decays involving \(\eta(1410)\) are presented, which can be tested at Beijing Electron Positron Collider/Beijing Spectrometer (BEPC/BES) with 50 million \(J/\psi\) events.
