摘要：

Using a sample of 5.8 x 10(7) J/psi events, the Beijing Spectrometer experiment has searched for the decay J/psi --> emu. Four candidates, consistent with the estimated background, are observed, and an upper limit on the branching fraction of J/psi --> emu of 1.1 X 10(-6) at the 90% C.L. is obtained.
