本文报道了我们在强子真空极化对μ子反常磁矩贡献的计算方面的进展。在这篇文章中,我们讨论了轻(上/下)夸克连接贡献的计算,使用我们在Phys.Rev. D89(2014)11,114501中描述的方法,并给出了非连接贡献的估计。我们的计算是在MILC协作组的$n_f = 2+1+1$ HISQ系综上进行的,在多重晶格间距、多重体积和多重轻海夸克质量(包括物理π质量组态)下进行的。
We report our (HPQCD) progress on the calculation of the Hadronic Vacuum Polarisation contribution to the anomalous magnetic moment of muon. In this article we discuss the calculations for the light (up/down) quark connected contribution using our method described in Phys.Rev. D89(2014) 11, 114501 and give an estimate for the disconnected contribution. Our calculation has been carried out on MILC Collaboration's $n_f = 2+1+1$ HISQ ensembles at multiple values of the lattice spacing, multiple volumes and multiple light sea quark masses (including physical pion mass configurations).
