The measurement of Born cross-section of [Formula: see text] process is one of the major goals of the future Circular Electron Positron Collider, which may reach a precision of 0.5% at 240 GeV. Such unprecedented precision must be guaranteed by both theoretical and experimental sides, such as the calculations of high order corrections, the knowledge of the [Formula: see text] line shape. Uncertainty of the radiative correction factor at 240 GeV caused by the [Formula: see text] line shape is evaluated in this work. Therefore, dedicated data-taking schemes are proposed in order to precisely calculate the ISR correction factor.

初始状态辐射校正及其对 σB(e+e−→ ZH) 测量数据采集方案的影响

[公式：见正文]过程的玻恩截面测量是未来圆形正负电子对撞机的主要目标之一，在240 GeV下可达到0.5%的精度。这种前所未有的精度，必须通过理论和实验两方面来保证，比如高阶修正的计算，[公式：见正文]线形的知识。在这项工作中评估了由 [公式：见正文] 线形引起的 240 GeV 辐射校正因子的不确定性。因此，为了精确计算 ISR 校正因子，提出了专门的数据采集方案。
