Interference effects in the decay ϕ\to π^{0}π^{0}γand the coupling constant g_{ϕσγ}

Abstract

We study the radiative decay $\varphi \to {\pi }^0{\pi }^0\gamma$ within the framework of a phenomenological approach in which the contributions of $\sigma$-meson, $\rho$-meson and $f_0$-meson are considered. We analyze the interference effects between different contributions and utilizing the experimental branching ratio for this decay we estimate the coupling constant $g_{\varphi \sigma \gamma }$.
