This analysis explores scalar effects in rho and omega decays, suggesting insights about the sigma meson properties.
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, where the effects of a low mass scalar resonance sigma (500)should manifest. The recently re-ported data on rho to pi^0 ;pi^0 gamma seem to require the contribution of a low mass and moderately narrow sigma(500). The properties of this controversial state could be fixed by improving the accuracy of these measurements. Data on omega to pi^0 pi^0 gamma can also be accommodated in our framework, but are much less sensitive to the sigma(500) properties.
