The omega to rho pi transition and omega to rho 3 pi decay

Abstract

We evaluate the omega to rho pi transition and the omega to 3 pi decay using a Quark Level Linear Sigma Model ($QL\sigma M$). We obtain $g_{\omega \rho \pi }^{QL\sigma M}=(10.33-14.75)Ge{V}^{-1}$ to be compared with other model dependent estimates averaging to $g_{\omega \rho \pi }=16Ge{V}^{-1}$. We show that in the $QL\sigma M$ a contact term is generated for the $\omega \to 3\pi$ decay. Although the contact contribution by itself is small, the interference effects turn out to be important.
