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 $g^{QL\sigma M}_{\omega\rho\pi}= (10.33 - 14.75) GeV^{-1}$ to be compared with other model dependent estimates averaging to $g_{\omega\rho\pi} = 16 GeV^{-1}$. We show that in the $QL...

The tetrahedron $A_4$ group has been widely used in studying neutrino mixing matrix. It provides a natural framework of model building for the tri-bimaximal mixing matrix. In this class of models, it is necessary to have two Higgs fields, $\chi$ and $\chi'$, transforming under $A_4$ as 3 with one of them having vacuu...
