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.
