英文摘要	By fitting the R values between 3.7 and 5.0 GeV measured by the BES Collaboration, the upper limit of the electron width of the newly discovered resonance Y(4260) is determined to be 580 eV/c(2) at 90% C.L. Together with the BaBar measurement on Gamma(ee) center dot B(Y(4260) -> pi(+)pi(-) J/psi), this implies a large decay width of Y (4260) -> pi(+)pi(-) J/psi final states. (c) 2006 Elsevier B.V.
