The Linear Sigma Model at Work: Succesful Postdictions for Pion Scattering

J. L. Lucio, M. Napsuciale, M. Ruiz-Altaba

We enforce chiral Ward identities on the vertices of the linear sigma model to take into account the width of the scalar sigma, considered as a true physical resonance. We consider…

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

J. L Lucio, M. Napsuciale, M. D. Scadron +1

We evaluate the omega to rho pi transition and the omega to 3 pi decay using a Quark Level Linear Sigma Model ( $Q L σ M$ ). We obtain $g_{ω ρ π}^{Q L σ M} = (10.33 - 14.75) G e V^{- 1}$ to be c…
