Scalar sigma meson effects in rho and omega decays into pi0 pi0 gamma

A. Bramon, R. Escribano, J. L. Lucio M. +1

The complementarity between Chiral Perturbation Theory and the Linear Sigma Model in the scalar channel is exploited to study ${\pi }^0{\pi }^0$ production in $\rho$ and $\omega$ radiative decays, w…
