Abstract: (arXiv)
Using a sample of 14 million ψ(2S) events accumulated with the BES II detector, evidence for f0(980)f0(980) production in χc0 decays is obtained for the first time/ the branching ratio is determined to be B(χc0→f0(980)f0(980)→π+π−π+π−)=(7.6±1.9(stat)±1.6(syst))×10−4. The significance of the f0(980) signal is about 4.6σ.- 14.40.Cs
