Abstract
We estimate the decay widths of the 0 ±-glueballs by taking account of the mixings with η and η′ through their anomalous coupling. We find a pseudoscalar glueball with a broad decay width, if its mass is larger than m δ(980) + m π . On the other hand, a scalar glueball has a narrow decay width. Assuming E(1440) to be the pseudoscalar glueball, we predict Γ δ(980) π π≈ 40 MeV.
