扩展的希格斯扇区出现在标准模型之外的许多物理模型中。目前在大型强子对撞机上进行的希格斯粒子测量已经开始对它们进行显著的限制。我们研究了它们的Higgs耦合模式在树的水平，以及包括量子校正。我们的基准测试包括一个暗单双扩展和几个双设置。使用SFitter，我们目前的希格斯耦合测量一个轻希格斯状态到各自的参数空间。最后，我们展示了如何twoHiggs-doublet模型可以作为一个一致的紫外线完成一个假设的单一的标准模型，像希格斯玻色子与自由耦合。
Extended Higgs sectors appear in many models for physics beyond the Standard Model. Current Higgs measurements at the LHC are starting to significantly constrain them. We study their Higgs coupling patterns at tree level as well as including quantum corrections. Our benchmarks include a dark singlet-doublet extension and several twodoublet setups. Using SFitter we translate the current Higgs coupling measurements for one light Higgs state into their respective parameter spaces. Finally, we show how twoHiggs-doublet models can serve as a consistent ultraviolet completion of an assumed single Standard-Model-like Higgs boson with free couplings.
