Abstract

The BES Collaboration has measured Ψ(2S)\Psi(2S) decay to J/Ψπ+πJ/\Psi \pi^+\pi^-. Using the mixed hybrid theory for the Ψ(2S)\Psi(2S) we estimate the decay to J/Ψ(1S)J/\Psi(1S) + σ\sigma. Using the known σ2π\sigma \rightarrow 2\pi coupling constant, we estimate the Ψ(2S)\Psi(2S) to J/Ψ(1S)J/\Psi(1S) + 2π2\pi decay rate and angular distribution. This is an extension of our previous research on Ψ(2S)\Psi(2S) Decay to J/Ψ(1S)J/\Psi(1S) +σ\sigma + 2πo\pi^o, without the production of 2πo\pi^o, and with an estimate of the σπ++π\sigma \rightarrow \pi^+ + \pi^- transition.
