Abstract

We study the effect of scalar-isoscalar f₀(980) meson in the mechanism of the radiative ϕ→ π⁺π^-γ decay. A phenomenological approach is used to study this decay by considering the contributions of σ-meson, ρ-meson and f₀(980)-meson. The interference effects between different contributions are analyzed and the branching ratio for this decay is calculated. We observe that f₀ meson contribution is much larger than the contributions of the other terms.
