摘　　要：北京谱仪 (BES)已收集了 2 5× 1 0 7个J/ ψ事例 ,并计划增加到 1 0 8— 1 0 9个 .本文综述近年来在BES上寻找新物理的研究 ,包括在J/ ψ衰变过程中探测新的味改变中性流 ,CP破坏和轻子味破坏 .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.
