The hadronic vacuum polarization of the muon fromfour-flavor lattice QCD

Abstract

LATTICE 2019, 7 pages, 7 figuresWe 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 ≈ 0.06 to 0.15 fm for most of the results thus far
