$J/\psi \to \gamma \pi \pi$, $\gamma {\pi }^0\eta$ reactions and the $f_0(980)$ and $a_0(980)$ resonances

We study the $J/\psi \to \gamma {\pi }^{+}{\pi }^{-}$, $\gamma {\pi }^0\eta$ reactions from the perspective that they come from the $J/\psi \to \varphi (\omega ){\pi }^{+}{\pi }^{-},{\rho }^0{\pi }^0\eta$ reactions, where the ${\rho }^0$, $\omega$, and $\varphi$ get convert…
