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