Abstract：
Beijing Spectrometer (BES) at Beijing Electron Positron Collider (BEPC),IHEP has accumulated 2.5×10⁷ J/ψ events and plans to increase this number to 10⁸—10⁹ in the near future. In this paper I review and summarize the recent studies on the possibilities of probing for new physics at BES. This includes the theoretical works on and experimental attempt performed at BES in searching for flavor changing neutral current,CP violation and lepton flavor violation in the processes of J/ψ decays.
