The decay $ρ^{0}\to π^{+}+π^{-}+γ$ and the coupling constant g$_{ρσγ}$

Abstract

The experimental branching ratio for the radiative decay $ρ^{0}\toπ^{+}+π^{-}+γ$ is used to estimate the coupling constant $g_{ρσγ}$ for a set of values of $σ$-meson parameters M$_σ$ and $Γ_σ$. Our results are quite different than the values of this constant used in the literature.
