Ψ(3770)扫描实验中Ψ(2S)部分数据积分亮度测量方法的研究

Study of the method for the measurement of the integrated luminosity of Ψ(2S) data in Ψ(3770) scan experiment

介绍Ψ(3770)扫描实验中Ψ(2S)部分数据积分亮度测量方法的研究,不仅考虑了QED产生过程,而且还考虑了Ψ(2S)共振产生过程及两者间的干涉效应,所研究的方法更适合于Ψ(2S)共振区内数据积分亮度的测定。

The method for the measurement of the integrated luminosity of BESII Ψ（2S） data in Ψ（3770） scan experiment is presented. Not only the processes of the QED production and Ψ（2S） resonance but also their interference effects are considered. It is more suitable to the measurement of the integrated luminosity of the data taken in the range of Ψ（2S） resonance.
