The Decays of Glueballs to two light mesons

Abstract

We solve the B.S. equation of glueballs under instantaneous approximation. With the B.S wave function obtained we calculate the decay width of glueballs to two pseudoscalar mesons, $\Gamma (\pi \pi )$, $\Gamma (kk)$ and $\Gamma (\eta \eta )$. $\Gamma (\eta {\eta }^{\prime })$ from QCD anomaly is also estimated.
