英文摘要 | Considering 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 into a pseudoscalar meson, we investigate 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 into a pseudoscalar meson. The quarkonia-glueball structure of eta, eta' and eta(1440) is phenomenologically deduced from the fit to the updated world average data concerning the above mentioned decays. We find that eta(eta') contains about 48.7%, 47.6%, 3.7% (32.9%, 48.8%, 18.3%) non-strange quarkonium, strange quarkonium and glueball components, respectively, and that eta(1410) is mainly a glueball state (about 78% glueball component), mixed with 18.5% non-strange quarkonium and 3.5% strange quarkonium. We predict that Br(J/psi --> gammaeta) : Br(J/psi --> gammaeta') : Br(J/psi --> gammaeta(1410)) = 1.0 : 5.2 : 8.0, which can be tested at BEPC/BES with 50 million J/psi events. |
