论文摘要
无效的是在大型强子撞机（LHC）上寻找新物理学的搜索倾向于强制相信新粒子必须比弱尺度重得多。我们对Higgs对齐和$ CP $抗衡的相互作用进行系统研究，以复杂的两-higgs-doublet模型进行，这使我们能够构建一个$ CP $ violation的场景，在该场景中，新的Higgs玻色子接近弱规模后，包括在电动型电动台上和测量中的严格约束，在LHC上进行了严格的限制。此外，我们提出了一个新颖的潜在信号，即希格斯至希格斯衰减中的$ cp $侵入，$ h_3 \ to h_2 h_1 $，其中$ h_3，h_2 $和$ h_1 $分别是最重的，第二重，是标准模型的中性higgs bosons。该衰减可以在$ H_1H_1H_1 $和$ H_1H_1Z $中以三重玻色子的最终状态表现出来，它们非常鲜明，并为LHC提供了新测量的独特场所。
Null results from searches for new physics at the Large Hadron Collider (LHC) tend to enforce the belief that new particles must be much heavier than the weak scale. We undertake a systematic study of the interplay between Higgs alignment and $CP$-violation in complex two-Higgs-doublet models, which enables us to construct a $CP$-violating scenario where new Higgs bosons are close to the weak scale after including stringent constraints from the electric dipole moment and measurements at the LHC. In addition, we propose a novel potential signal of $CP$-violation in the Higgs-to-Higgs decays, $h_3\to h_2 h_1$, where $h_3, h_2$, and $h_1$ are the heaviest, second heaviest and the Standard Model-like neutral Higgs bosons, respectively. The decay could manifest itself in triple boson final states in $h_1h_1h_1$ and $h_1h_1Z$, which are quite distinct and provide unique venues for new measurements at the LHC.
