在正负电子对撞的能量扫描实验中测量R值时，事件产生器中需要对初态辐射进行精确计算。我们提出了一个考虑到这一点的事件产生器，它包含初态辐射（最后一个单词“radiat”不完整，可能影响准确理解）
To measure the R value in an energy scan experiment with e(+)e(-) collisions, precise calculation of initial state radiation is required in the event generators. We present an event generator for this consideration, which incorporates initial state radiation effects up to second order accuracy. The radiative correction factor is calculated using the totally hadronic Born cross section. The measured exclusive processes are generated according to their cross sections, while the unknown processes are generated using the LUND Area Law model, and its parameters are tuned with data collected at root s = 3.65 GeV. The optimized values are validated with data in the range root s = 2.2324-3.671 GeV. These optimized parameters are universally valid for event generation below the DD threshold.
