Abstract

The decay rates of

ω \to 3 π

,

η \to π^{+} π^{-} γ

,

X^{0} \to π^{+} π^{-} γ

,

η \to π^{0} γ γ

, and

X^{0} \to π^{0} γ γ

are calculated using a chiral Lagrangian model suggested previously. The effects of the contact interaction and the

σ

-pole terms in these decay modes are studied in detail.
