Description
Evidence of ψ(3770) decays to a non-DD-bar final state is observed. A total of 11.8+/-4.8+/-1.3ψ(3770)->J/ψπ+π- events are obtained from a data sample of 27.7 pb-1 taken at center-of-mass energies around 3.773 GeV using the BES-II detector at the BEPC. The branching fraction is determined to be BF(ψ(3770)->J/ψπ+π-)=(0.34+/-0.14+/-0.09)%, corresponding to the partial width of Γ(ψ(3770)->J/ψπ+π-)=(80+/-33+/-23) keV
