We obtain $g^{QLσM}_{ωρπ}= (10.33 - 14.75) GeV^{-1}$ to be compared with other model dependent estimates averaging to $g_{ωρπ} = 16 GeV^{-1}$. We show that in the $QLσM$ a contact term is generated for the $ω\to 3 π$ decay. Although the contact contribution by itself is small, the interference effects turn out to be important.12 pages, LaTeX, 3 eps figures, uses epsf.styHigh Energy Physics - Phenomenologytext
