Abstract :
Mark III data on JΨ → γ(π+π−π+π−) have been re-analysed including γσσ final states as well as γϱϱ. Here σ stands for the ππ S-wave amplitude. We fit with I = 0 resonances having JPC = 2++ at 1275 MeV, 0−+ at 1420 MeV, 0++ at 1505 MeV, 2++ at 1640 MeV, 0++ at 1750 MeV and 0++ at 2104 MeV. The 0++ resonances decay dominantly to σσ and the 2++ resonances to ϱϱ.
