论文摘要
我们计算两个过程中的完整单循环辐射校正（包括弱和QED校正）$ e^{+} e^{ - } \至z h^0，higgs higgs doublet模型（ihdm）中的h^0 a^{0 a^{0 a^{0} $。最多$ o（α_{w}）$和$ o（α_{em}）$订单，我们使用feynarts/formcalc计算单循环虚拟校正和Feynman图计算（FDC）来评估真实的发射。我们配备了这些计算工具，我们研究了对退化和非分类场景的新物理学的辐射校正，并具有三个典型的Electron-positron Colliders典型碰撞能量：250 GEV，500 GEV和1000GEV。通过扫描IHDM的参数空间，我们可以从理论和实验方面确定与约束和边界一致的允许区域。我们发现，IHDM至$ e^+ e^ - \至z H^0 $的辐射校正可能很大，并且在未来Higgs工厂的检测潜力范围内。我们还发现，通过观察该过程$ e^{+} e^{ - } \ to H^0 a^{0} $，它也可以直接检测到IHDM的新物理学，从而具有足够的生产率。我们提出了五个基准点并检查它们的显着特征，这些特征可以用作将来电子脉络膜山脉的物理靶标，例如CEPC/CLIC/CLIC/FCC-EE/ILC以及LHC。
We compute the full one-loop radiative corrections (including both weak and QED corrections) for two processes $e^{+}e^{-}\to Z h^0,H^0 A^{0}$ in the Inert Higgs Doublet model (IHDM). Up to $O(α_{w})$ and $O(α_{em})$ order, we use FeynArts/FormCalc to compute the one-loop virtual corrections and Feynman Diagram Calculation (FDC) to evaluate the real emission, respectively. Being equipped with these computing tools, we investigate radiative corrections of new physics for both the degenerate and non-degenerate scenarios with three typical collision energies of future electron-positron colliders: 250 GeV, 500 GeV, and 1000GeV. By scanning the parameter space of IHDM, we identify the allowed regions which are consistent with constraints and bounds, from both theoretical and experimental sides. We find that the radiative corrections of the IHDM to $e^+ e^- \to Z h^0$ can be sizeable and are within the detection potentials of future Higgs factories. We also find that the new physics of IHDM could also be directly detected by observing the process $e^{+}e^{-}\to H^0 A^{0} $ which could have large enough production rate. We propose five benchmark points and examine their salient features which can serve as physics targets for future electron-positron colliders, such as CEPC/CLIC/FCC-ee/ILC as well as for LHC.
