摘要
回顾了世界各实验组在类时和类空过程中电磁形状因子的测量状况,根据BES 上R值扫描所获取的2.0~3.0GeV各能量点的数据,探讨如何在BES上测量类时过程的质子电磁形状因子,最后结合BES 给出对该实验的展望.
This paper gives a review of measurements of proton elecmagnetic form factors in spacelike and timelike region, repectively. The approach to measure proton elecmagnetic form factors in timelike region on BESⅡ with R scan data between 2.0~3.0 GeV is presented. Finally, it studies the feasibility and prospect of this work on BESⅢ.
