Sigma and Pion Decays of Mixed Heavy Hybrids

Abstract

We estimate the relative branching ratio of $\sigma$ to 2$\pi$ for the decay of the ${\Psi }^{\prime }(2S)$, which we have found to be a mixed charm and hybrid charmonium meson. The external field method and correlators from a previous calculation are used to estimate these decays. We find the $\sigma$ to 2$\pi$ branching ratio for ${\Psi }^{\prime }(2S)$ to the $J/\Psi (1S)$ decay to be 0.98, in agreement with an experiment at IHEP-BES.
