论文摘要
在标准模型之外搜索物理签名的最有希望的数量之一是MUON的异常磁矩$ G-2 $，在此，将实验结果与标准模型估计的比较得出约3.5 〜σ $的偏差。在理论方面，最大的不确定性来自辐射部门，即强烈的真空极化和悬灯散射。我回顾了从晶格中计算出对MUON $ G-2 $的HADRONIC贡献方面的最新进展，并讨论了与即将到来的实验相匹配的前景和挑战。
One of the most promising quantities for the search of signatures of physics beyond the Standard Model is the anomalous magnetic moment $g-2$ of the muon, where a comparison of the experimental result with the Standard Model estimate yields a deviation of about $3.5~σ$. On the theory side, the largest uncertainty arises from the hadronic sector, namely the hadronic vacuum polarisation and the hadronic light-by-light scattering. I review recent progress in calculating the hadronic contributions to the muon $g-2$ from the lattice and discuss the prospects and challenges to match the precision of the upcoming experiments.
