我们考虑了标准模型(SM)的标量扩展及其有效场论的推广,以说明Muon反常磁矩的精确测量、精密Higgs测量和直接对撞器灵敏度之间的唯象联系。为此,我们考虑带电超越标准模型(BSM)的Zee-Babu类型的标量扇区,我们为其发展了一致和完整的5维和6维有效场论扩展。这使我们能够追踪主要通过辐射相互作用与SM相互作用的通用新物理效应。虽然算符空间是高维的,但在大型强子对撞机(LHC)、希格斯信号强度和反常Muon磁性测量中,异类搜索的交集很小。我们发现,LHC-Higgs观测的一致性需要新的态的电弱性质的显著变形。LHC实验目前在寻找双电荷标量方面的证据可以用来进一步拉紧BSMEFT参数空间,并解决有效场论(EFT)扩展的Zee-Babu情景中的盲目方向。
We consider scalar extensions of the Standard Model (SM) and their effective field theoretic generalizations to illustrate the phenomenological connection between precision measurements of the anomalous magnetic moment of the muon, precision Higgs measurements, and direct collider sensitivity. To this end, we consider charged beyond Standard Model (BSM) scalar sectors of the Zee-Babu type for which we develop a consistent and complete dimension-5 and -6 effective field theory extensions. This enables us to track generic new physics effects that interact with the SM predominantly via radiative interactions. While the operator space is high dimensional, the intersection of exotics searches at the Large Hadron Collider (LHC), Higgs signal strength, and anomalous muon magnetic measurements is manageably small. We find that consistency of LHC Higgs observations andrequires a significant deformation of the new states’ electroweak properties. Evidence in searches for doubly charged scalars as currently pursued by the LHC experiments can be used to further tension the BSMEFT parameter space and resolve blind directions in the effective field theory (EFT)-extended Zee-Babu scenario.
