Scalar mesons in radiative \phi\to K^0\bar{K}^0\gamma decay

Abstract

We study the radiative $\varphi \to K^0{\bar{K}}^0\gamma$ decay within a phenomenological framework by considering the contributions of the $f_0(980)$ and $a_0(980)$ scalar resonances. We calculate the branching ratio $B(\varphi \to K^0{\bar{K}}^0\gamma )$ by employing the coupling constants $g_{f_0{K}^{+}{K}^{-}}$ and $g_{a_0{K}^{+}{K}^{-}}$ as determined by different experimental groups.
