Özet

We study the radiative decay phi --> pi (0)pi (0)gamma within the framework, of a phenomenological approach in which the contributions of sigma mesons, rho mesons, and f(0) mesons 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(phi sigma gamma).
