论文摘要
标准模型（SM）很好地描述了在大型强子对撞机上发现的希格斯玻色子的性质。因此，任何援引扩展的希格斯部门的理论都必须解释为什么在LHC上观察到的中性标量如此之类似于Sm Higgs玻色子。在这次演讲中，我回顾了希格斯对准极限，其中希格斯扇区的一个中性标量状态很像。可以通过解耦或近似对称性“自然地”实现近似的希格斯对齐。我使用两双双双球模型作为扩展希格斯扇区的原型，我检查了标量电势的对称性及其软断裂的对称性，这些柔软断裂可能导致了观察到的希格斯玻色子的Smike属性，并且我证明了如何扩展（柔和的）与Yukawa部门的符号。
The properties of the Higgs boson discovered at the Large Hadron Collider are very well described by the Standard Model (SM). Thus, any theory that invokes an extended Higgs sector must explain why the neutral scalar observed at the LHC so closely resembles the SM Higgs boson. In this talk, I review the Higgs alignment limit, in which one neutral scalar state of the Higgs sector is SM-like. An approximate Higgs alignment can be achieved "naturally" either via decoupling or via an approximate symmetry. Using the two-Higgs doublet model as a prototype for an extended Higgs sector, I examine the symmetries of the scalar potential and their soft breakings that may be responsible for the SM-like properties of the observed Higgs boson, and I demonstrate how to extend such (softly-broken) symmetries to the Yukawa sector of the model.
