论文摘要
我们研究了$ \ mathbb {z} _4 $基于两个基于两个Higgs Doublet模型的大型强子对撞机（LHC）搜索潜力，该模型可以同时解释Muon $ G-2 $异常和观察到的暗物质。第二个Higgs Doublet夫妇中的中性标量至$μ$和$τ$，并且通过涉及$τ$和标量的一环图，在很大程度上有助于MUON异常磁矩。在离散对称性下收取的其他单点标量可能是暗物质的候选者。标量质量的上限起源于单位性约束，标量的$μτ$风味侵入性可以预测LHC处的非标准性特征。但是，先前提出的$μ^\pmμ^\pmτ^\mpτ^\ mp $通过electroweak重型中性标量对生产在LHC处失去了增加标量质量的敏感性。我们重新审视该模型，并研究了$μτ$风味侵入中性标量的单一产生的LHC前景。结果表明，单个标量过程有助于将LHC扩展到场景的1 $ \ $ tev质量制度。还讨论了高能LHC的搜索潜力。
We study the Large Hadron Collider (LHC) search potential of a $\mathbb{Z}_4$-based two Higgs doublet model which can simultaneously explain the muon $g-2$ anomaly and the observed dark matter. The neutral scalars in the second Higgs doublet couple to $μ$ and $τ$ and largely contribute to the muon anomalous magnetic moment through the one-loop diagram involving $τ$ and scalars. An additional singlet scalar which is charged under the discrete symmetry can be a dark matter candidate. An upper limit on the scalar mass originates from the unitarity constraint, and the $μτ$ flavor-violating nature of the scalars predicts non-standard signatures at the LHC. However, the previously proposed $μ^\pmμ^\pmτ^\mpτ^\mp$ signal via the electroweak heavy neutral scalar pair production at the LHC loses sensitivity for increasing scalar mass. We revisit this model and investigate the LHC prospects for the single production of the $μτ$ flavor-violating neutral scalar. It is shown that the single scalar process helps to extend the LHC reach to the 1$\,$TeV mass regime of the scenario. The search potential at the high energy LHC is also discussed.
