论文摘要
我们考虑了MUON $A_μ$的异常磁矩，鉴于Fermilab和BNL的最新测量值，它与标准模型期望的显着偏差。我们专注于标准模型有效现场理论（SMEFT），目的是确定即将到来的LHC运行和未来实验（例如Muone）的途径。为此，我们将辐射效果包括在$a_μ$的中性企业中，以将MUON异常与LHC的潜在有趣的搜索联系起来，特别是Higgs衰减到MUON对，并在解决的光子上腐烂。我们的研究表明，与标准模型的混凝土紫外线扩展的结果相似，Fermilab/BNL结果可能表明在EFT框架内进行强耦合，并且$A_μ$对单个操作员的方向越来越敏感。在这种情况下，预期的未来实验改进之间存在一些互补性，但是由于统计挑战符合最近的$A_μ$测量值的精确度。
We consider the anomalous magnetic moment of the muon $a_μ$, which shows a significant deviation from the Standard Model expectation given the recent measurements at Fermilab and BNL. We focus on Standard Model Effective Field Theory (SMEFT) with the aim to identify avenues for the upcoming LHC runs and future experiments such as MUonE. To this end, we include radiative effects to $a_μ$ in SMEFT to connect the muon anomaly to potentially interesting searches at the LHC, specifically Higgs decays into muon pairs and such decays with resolved photons. Our investigation shows that similar to results for concrete UV extensions of the Standard Model, the Fermilab/BNL result can indicate strong coupling within the EFT framework and $a_μ$ is increasingly sensitive to a single operator direction for high scale UV completions. In such cases, there is some complementarity between expected future experimental improvements, yet with considerable statistical challenges to match the precision provided by the recent $a_μ$ measurement.
