Abstract
The η′(960) and ι(1440) are treated as glueballs in the framework of effective chiral lagrangians which satisfy the axial anomaly equation. The narrow width of the η′ can be qualitatively understood. An associated large breaking of flavor SU(3) is shown to be ameliorated as the model is made more realistic by lowering scalar meson masses from infinity. The π δ decay of the ι(1440) can be reasonably well estimated without the need of introducing any new parameters.
