Abstract: (arXiv)
Using a sample of 14 million events accumulated with the BES II detector, evidence for production in decays is obtained for the first time/ the branching ratio is determined to be . The significance of the signal is about 4.6.- 14.40.Cs
- 13.25.Gv
- electron positron: colliding beams
- electron positron: annihilation
- psi(3770): electroproduction
- chi/c2(3555): hadronic decay
- f0(980): pair production
- f0(980): hadronic decay
- mass spectrum: (2pi+ 2pi-)
- chi/c2(3555): branching ratio
