Search for Lepton Flavor Violation Process J/$\psi \to e\mu$

Abstract

Using a sample of 5.8X10E7 J/$\psi$ events, the Beijing Spectrometer experiment has searched for the decay J/$\psi \to e\mu$. Four candidates, consistent with the estimated background, are observed, and an upper limit on the branching fraction of J/$\psi \to e\mu$ of 1.1X10E-6 at the 90% C.L. is obtained.
