北京谱仪在北京正负电子对撞机上的进展

Progress of BES at BEPC

摘要: 本文简要介绍北京谱仪在北京正负电子对撞机上的进展。概述了北京正负电子对撞机和北京谱仪的性能,北京谱仪在J/ψ物理方面获取的初步结果及在τ质量测量方面的阶段状况. The progress of Beijing Electron Spectrometer (BES) at the Beijing Electron-Positron Collider (BEPC) are introduced here briefly.The major performance of the BEPC and BES,the preliminary results on J/Ψ physics and the status of τ mass measurment aredescribed.
