摘要:

FERMILAB的μ子g-2实验证实了μ子异常磁矩异常,与以前的Brookhaven结果相比,误差条小15%,中心值不同。FERMILAB和Brookhaven的综合结果显示了与理论的差异,其显著性为$4.2σ$,强烈表明了新物理的存在。根据这一新的结果,我们讨论了一个由阿贝尔规范对称性增强的双希格斯双重模型,该模型可以同时容纳一个轻暗物质候选者和$(g-2)_μ$,与现有的边界一致。

英文摘要:

The Muon g-2 experiment at FERMILAB has confirmed the muon anomalous magnetic moment anomaly with an error bar 15% smaller and a different central value compared with the previous Brookhaven result. The combined results from FERMILAB and Brookhaven show a difference with theory at a significance of $4.2σ$, strongly indicating the presence of new physics. In light of this new result, we discuss a Two Higgs Doublet model augmented by an Abelian gauge symmetry that can simultaneously accommodate a light dark matter candidate and $(g-2)_μ$, in agreement with existing bounds.
