Modification of Kawai model about the mixing of the pseudoscalar mesons

Abstract

The Kawai model describing the glueball-quarkonia mixing is modified. The mixing of $\hat{I}\cdot$, $\hat{I}{\cdot }^{\prime }$ and $\hat{I}\cdot (1410)$ is re-investigated based on the modified Kawai model. The glueball-quarkonia content of the three states is determined from a fit to the data of the electromagnetic decays involving $\hat{I}\cdot$, $\hat{I}{\cdot }^{\prime }$. Some predictions about the electromagnetic decays involving $\hat{I}\cdot (1410)$ are presented.
