论文摘要
我们探索了违反Lepton风味的参数空间（LFV）中性希格斯与Muon和Tau Leptons的中性希格斯（Yukawa）耦合，可以通过矢量玻色子融合〜（VBF）HIGGS HIGGS HIGGS HIGGS HIGGS HIGGS HIGGS HIGGS HIGGS HIGGS HIGGS HIGGS HIGGS HIGGS HIGGS HIGGS HIGGS HIGGS HIGGS生产过程。我们对标准模型Higgs（$ h $）LFV分支比率$ {\ rm br}（\ rm br}（h \ toμτ）$中的敏感性与当前和未来约束的频率与HL-LHC的HL-LHC造成了矛盾以及其他LFV可观察物，例如$τ\至3μ$和$τ\至μγ$。我们还研究了超出标准模型中性希格斯玻色子（$ h $）的通用型号的LFV前景，其质量为$ m_ {h} \ in [20,800]〜$ GEV，并给出了预计的与模型无关的上限，并在$ hjj $ $ hjj $ times $ hjj $ times $ hjj $ hjj $ hjj $ hjj $ hjj $ hjj $ hj $ hj $ hj $ hj $ hj $ ftch中提供了群体的上限。我们将这些结果解释为在两双双重双体模型的背景下作为案例研究。
We explore the parameter space of lepton flavor violating (LFV) neutral Higgs Yukawa couplings with the muon and tau leptons that can be probed at the high-luminosity Large Hadron Collider (HL-LHC) via the vector boson fusion~(VBF) Higgs production process. Our projected sensitivities for the Standard Model Higgs ($h$) LFV branching ratio ${\rm Br}(h \to μτ)$ in the $pp \to h j j \to (h \to μτ) jj$ channel at the HL-LHC are contrasted with the current and future low-energy constraints from the anomalous magnetic moment and electric dipole moment of the muon, as well as with other LFV observables, such as $τ\to 3μ$ and $τ\to μγ$. We also study the LFV prospects of a generic beyond the Standard Model neutral Higgs boson ($H$) with a mass in the range of $m_{H}\in [20,800]~$GeV and give the projected model-independent upper limits on the VBF production cross-section of $Hjj$ times the branching ratio of $H\to μτ$ at the HL-LHC. We interpret these results in the context of a two-Higgs doublet model as a case study.
