论文摘要
我们讨论了近距离二合一模型的黑暗阶段。该模型是标准模型的扩展，具有额外的双打和一个额外的单线，该单元具有四个不同的CP支持阶段，其中三个提供了暗物质候选者。我们详细讨论了不同阶段的真空结构以及每个阶段的树层的稳定性问题。考虑到最相关的实验和理论约束，我们发现大型强子对撞机的测量值组合可能会单列特定阶段。 $ h_ {125} \至γγ$的测量以及发现具有特定速率为$τ^+τ^ - $或$γγ$的新标量可以将某些阶段排除并指向特定阶段。
We discuss the dark phases of the Next-to-2-Higgs Doublet model. The model is an extension of the Standard Model with an extra doublet and an extra singlet that has four distinct CP-conserving phases, three of which provide dark matter candidates. We discuss in detail the vacuum structure of the different phases and the issue of stability at tree-level of each phase. Taking into account the most relevant experimental and theoretical constraints, we found that there are combinations of measurements at the Large Hadron Collider that could single out a specific phase. The measurement of $h_{125} \to γγ$ together with the discovery of a new scalar with specific rates to $τ^+ τ^-$ or $γγ$ could exclude some phases and point to a specific phase.
