摘要: We estimate the decay rate of the Ψ(2S) to J/Ψ(1S) + 2π and σ + 2π. This is based on the mixed hybrid theory that was developed for the Ψ(2S) and was used to estimate the ratio Ψ(2S)→J/Ψ(1S)+σ to Ψ(2S)→J/Ψ(1S)+2π in 2011. A main motivation of the present work is to predict the possible experimental detection of the decay of Ψ(2S) to J/Ψ(1S)+σ+2π, or possibly to J/Ψ(1S)+2π+glueball.
