给出了希格斯工厂中对过程$e^+ e^- \to Z \phi $ ($\phi=h^0,H^0$)的完整单环修正,包括弱修正和QED修正。直到$O(\alpha_{EM})$级别,虚拟修正在费曼图解方法中进行评估。利用费曼图计算(FDC)系统计算了实际发射改正量,并用电子的结构函数正则化了共线发散。利用FDC系统,我们分别研究了SM模型和两个希格斯双重态模型(2HDM)中的修正。在考虑到当前LHC数据的实验限制后,我们为未来的对撞机提出了四种有趣的2HDM基准场景。通过使用这些基准场景,我们评估$ \Delta\sigma(e^+ e^- \to Z \phi)$与其标准模型(SM)值的偏差。我们还研究了$\phi\to b\bar{b}$和$\phi\to \tau^+\tau^-$,它们可能从三重希格斯耦合中获得大量的电子波贡献,而这在SM中是不存在的。研究发现,在这些基准情景下,电子束和实际发射校正都是相当大的,可以在未来的$e^+ e^-$对撞机}上测量,如ILC、CLIC和CEPC。
The full one-loop corrections, both the weak and QED corrections, to the process $e^+ e^- \to Z \phi $ ($\phi=h^0,H^0$) at the Higgs factories are presented. Up to the $O(\alpha_{EM})$ level, the virtual corrections are evaluated in a Feynman-diagrammatic approach. The real emission corrections are computed using Feynman Diagram Calculation (FDC) system and the collinear divergences are regularized by the structure functions of electron. Using the FDC system, we study the corrections both in the SM and the two Higgs doublet model (2HDM), respectively. After taking into account experimental constraints from the current LHC data, we propose four interesting benchmark scenarios of 2HDM for future colliders. By using these benchmark scenarios, we evaluate the deviation of $ \Delta\sigma(e^+ e^- \to Z \phi)$ from their Standard Model (SM) values. We also examine $\phi\to b\bar{b}$ and $\phi\to \tau^+\tau^-$, which may receive large EW contribution from triple Higgs couplings which are absent in the SM. It is found that for these benchmark scenarios, both EW and real emission corrections are sizable and could be measured at a future $e^+ e^-$ collider} such as the ILC, CLIC and CEPC.
