Study of J/ψ、γπ0π0 at BES

  • Institute of High Anergy Physics, CAS, Beijing 100039

Abstract: The decay J/ψ→γπ0π0 is studied with 7.0×106 produced J/ψ events collected by the Bening Spectrometer(BES) with the tugger mode senseuve to both chmped and neutral final state at the Bening Electron-Positron Collider(BEPC), The evidences for the existence of fJ(1710) and E(2230) in this channel are presented, and the corresponding masses as wen asthe product branching ratios are obtained.
