Interference effects in the decay Ï\to Ï^{0}Ï^{0}Î³and the coupling constant g_{ÏÏÎ³}

arXiv:hep-ph/0106211 · doi:10.1103/PhysRevD.64.053017

Abstract

We study the radiative decay $Ï\toÏ^{0}Ï^{0}Î³$ within the framework of a phenomenological approach in which the contributions of $Ï$-meson, $Ï$-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 $g_{ÏÏÎ³}$.
