Abstract

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