Decay Modeω→2π+γ

Abstract

The width of the decay mode $\omega \to 2\pi +\gamma$ is calculated, assuming that it proceeds through a ($\rho \pi$) intermediate state. The $\gamma$ energy spectrum, which happens to be strongly asymmetric, is also presented. The ratio $\frac{(\omega \to 2\pi +\gamma )}{(\omega \to 3\pi )}$ is evaluated by using two different theoretical models and it is concluded that the $2{\pi }^0+\gamma$ mode is appreciably less frequent than the ${\pi }^0+\gamma$ mode. Finally, the experimental implications are discussed.
