Scalar $f_{0}(980)$ meson effect in radiative $ϕ\to π^{+}π^{-}γ$ decay

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/43429We study the effect of scalar-isoscalar $f_{0}(980)$ meson in the mechanism of the radiative $ϕ\to π^{+}π^{-}γ$ decay. A phenomenological approach is used to study this decay by considering the contributions of $σ$-meson, $ρ$-meson and $f_{0}(980)$-meson. The interference effects between different contributions are analyzed and the branching ratio for this decay is calculated. We observe that $f_0$ meson contribution is much larger than the contributions of the other terms.7 pagesHigh Energy Physics - PhenomenologyScalar $f_{0}(980)$ meson effect in radiative $ϕ\to π^{+}π^{-}γ$ decaytext
