Abstract

The scalar meson exchange in ϕP0P0γ\phi\to P^0 P^0\gamma decays is discussed in a chiral invariant framework where the scalar meson poles are incorporated explicitly. ϕπ0π0γ\phi\to\pi^0\pi^0\gamma and ϕπ0ηγ\phi\to\pi^0\eta\gamma are in agreement with recent experimental data and can be used to extract valuable information on the properties of f0(980)f_{0}(980) and a0(980)a_{0}(980) respectively. ϕK0Kˉ0γ\phi\to K^0\bar K^0\gamma is shown not to pose a background problem for testing CP violation at DaΦ\Phine. The ratio ϕf0γ/a0γ\phi\to f_{0}\gamma/a_{0}\gamma is also predicted.
