$\mathrm{\Psi }(2S)$ decay to $J\mathrm{/}\mathrm{\Psi }(1S)$ +2$\pi$ or $J\mathrm{/}\mathrm{\Psi }(1S)$ + $\sigma$ + 2$\pi$

The BES Collaboration has measured $\mathrm{\Psi }(2S)$ decay to $J\mathrm{/}\mathrm{\Psi }{\pi }^{+}{\pi }^{-}$. Using the mixed hybrid theory for the $\mathrm{\Psi }(2S)$ we estimate the decay to $J\mathrm{/}\mathrm{\Psi }(1S)$ + $\sigma$. Using the known $\sigma \to 2\pi$ coupling constant, we estimate the $\mathrm{\Psi }(2S)$ to $J\mathrm{/}\mathrm{\Psi }(1S)$ + $2\pi$ decay rate and angular distribution. This is an extension of our previous research on $\mathrm{\Psi }(2S)$ Decay to $J\mathrm{/}\mathrm{\Psi }(1S)$ +$\sigma$ + 2${\pi }^o$, without the production of 2${\pi }^o$, and with an estimate of the $\sigma \to {\pi }^{+}+{\pi }^{-}$ transition.
