Study of J/Ψ → γ π0 π0 at BES
- 1. Academia Sinica, Beijing (China). Inst. of High Energy Physics
Description
The decay J/Ψ→γπ0π0 is studied with 7.0 x 106 produced J/Ψ events collected by the Beijing Spectrometer (BES) with the trigger mode sensitive to both charged and neutral final state at the Beijing Electron-Positron Collider (BEPC). The evidences for the existence of FJ(1710) and ξ(2230) in this channel are presented, and the corresponding masses as well as the product branching ratios are obtained
