phi -> pi0 pi0 gamma Decay within a U(3)x U(3) Linear Sigma Model

J. L. Lucio, M. Napsuciale

We show that therecently observed pion invariant mass distribution of the phi ->pi0 pi0 gamma decay can be satisfactorily described by the chiral U(3) X U(3) Linear Sigma Model.

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…

$γ γ \to π^{0} π^{0}$ as a test for the existence of a light $σ$ meson

J. L. Lucio, G. Moreno, M. Napsuciale +1

We work out predictions of the Linear Sigma Model for the $γ γ \to π^{0} π^{0}$ cross section. We consider the sigma width, which is introduced in a consistent way with chiral Ward identi…
