Description
A chiral field theory of $0^{-+}$ glueball is presented. The Lagrangian of this theory is constructed
by adding a $0^{-+}$ glueball field to a
successful Lagrangian of chiral field theory of pseudoscalar, vector, and axial-vector mesons.
The couplings between the pseodoscalar glueball field and
the mesons are via U(1) anomaly revealed.
Quantitative study of the physical processes of the $0^{-+}$ glueball of $m=1.405\textrm{GeV}$ is presented.
In this talk following topics are presented:
a new chiral field theory of $0^{-+}$ glueball;
mass mixing between $\eta, \eta',\;and \; 0^{-+}$($\eta(1405)$) glueball;
kinetic mixing;
$J/\psi\rightarrow\gamma\eta(1405)$ decay;
$\eta(1405)\rightarrow\gamma\gamma, \gamma\rho, \gamma\omega, \gamma\phi, \gamma\pi\pi, \gamma KK$ decays;
$\eta(1405)\rightarrow\rho\pi\pi$ and strong decays of $\eta(1405)$.
The theoretical predictions can be used to identify the $0^{-+}$ glueball.
