论文摘要
大型强子对撞机（LHC）与标准模型（SM）的较重粒子（SM）测量了Higgs玻色子耦合，并且如SM所示，它们似乎位于粒子质量的函数上。但是，对该属性的完整测试必须涉及较轻的世代，而LHC或将来的山脉的即将到来的测量可能会揭示与SM之外的物理相关的隐藏模式。在可重大的多基金模型中，Higgs-Fermion耦合仍然可以是线性的，但它们可以放在多条线上。然后，这些线与SM线相对于SM线的角度可用于表征不同的模型，如下所示，这是针对两-higgs Doublet模型（2HDM）所示。费米昂质量来自高维操作员的模型，也可能导致与Higgs耦合的SM值的较大偏差，这将显示出不规则的模式，这是费米昂质量的函数。在中微子质量的情况下，当它们源于远见机制时，人们发现Yukawa耦合将显示出非线性的质量关系。
The Large Hadron Collider (LHC) has measured the Higgs boson couplings with the heavier particles of the Standard Model (SM), and they seem to lay on a single line as function of the particle mass, as predicted in the SM. However a complete test of this property must involve the lighter generations, and the coming measurements at LHC, or future colliders, may reveal hidden patterns associated with physics beyond the SM. In renormalizable multi-Higgs models, the Higgs-fermion couplings could still be linear, but they could lay on multiple lines. Then, the angle subtended by these lines, with respect to the SM line, can be used to characterize different models, as it is shown here for the Two-Higgs doublet Model (2HDM). Models where fermion masses arise from higher-dimensional operators, may also result in large deviations from the SM values for the Higgs couplings, which would show an irregular pattern as a function of the fermion masses. In the case of neutrino masses, when they arise from the see-saw mechanism, one finds that the Higgs Yukawa couplings will show a non-linear mass relation.
