论文摘要
我们研究了具有矢量样瘦素和可口标量扇形的标准模型扩展的对撞机特征。这种框架自然会在渐近安全的模型构建中产生，该框架构成了标准模型对普朗克量表及其他地区的紫外线行为。我们专注于Yukawa耦合和质量的值，这些值可以解释有关MUON和电子异常磁矩的当前数据。使用基于$ 77.4 \，\ rm {fb}^{ - 1} $的CMS搜索在$ \ sqrt {s} = 13 $ tev lhc处使用，我们发现，如果他们在$ 300 $ 300 $左右的$ 300 $ sukelets yflufe $ 300 $ 300 $ s的$ 300 $ su（如果他们是$ su（2）$ 800 $ 800 $ 800 $ 800 $ 800 $ 800 $ 800 $ 800 $ 800。利用标量的类似风味的侵略性衰减，我们根据相反的风味不变质量设计了新颖的无效可观察物。这些多级分布允许向新物理学发出信号，并提取LHC和HL-LHC近距离搜索的质量层次结构。
We investigate collider signatures of standard model extensions featuring vector-like leptons and a flavorful scalar sector. Such a framework arises naturally within asymptotically safe model building, which tames the UV behavior of the standard model towards the Planck scale and beyond. We focus on values of Yukawa couplings and masses which allow to explain the present data on the muon and electron anomalous magnetic moments. Using a CMS search based on $77.4 \, \rm{fb}^{-1}$ at the $\sqrt{s}=13$ TeV LHC we find that flavorful vector-like leptons are excluded for masses below around $300$ GeV if they are singlets under $SU(2)_L$, and around $800$ GeV if they are doublets. Exploiting the flavor-violating-like decays of the scalars, we design novel null test observables based on opposite sign opposite flavor invariant masses. These multi-lepton distributions allow to signal new physics and to extract mass hierarchies in reach of near-future searches at the LHC and the HL-LHC.
