摘要

我们提出了Fermilab Lattice, HPQCD和MILC协作正在进行的计算的更新,这些计算是关于(电磁学)强子真空极化对μ子异常磁矩的贡献。到目前为止,我们的项目采用了四种高度改进的交错费米子、物理光夸克质量和四种晶格间距(从$ 0.06$到0.15 fm)的组合,大多数结果都是如此。

The hadronic vacuum polarization of the muon fromfour-flavor lattice QCD
We present an update on the ongoing calculations by the Fermilab Lattice, HPQCD, and MILC Collaboration of the leading-order (in electromagnetism) hadronic vacuum polarization contribution to the anomalous magnetic moment of the muon. Our project employs ensembles with four flavors of highly improved staggered fermions, physical light-quark masses, and four lattice spacings ranging from $a \approx 0.06$ to 0.15 fm for most of the results thus far.
