Description
The recent experimental result for the muon’s anomalous magnetic
moment from Fermilab motivates the reduction of the errors on lattice
QCD calculations of the leading order hadronic contribution. All of our
calculations use the highly-improved staggered quark (HISQ)
formulation. The gauge configurations are generated with four flavors
of HISQ sea quarks with physical sea-quark masses. The disconnected
QCD calculation use configurations at the three lattice spacings:
0.15, 0.12 and 0.09 fm. We report preliminary results for some of the
QED+QCD contributions at one lattice spacing, which use either
quenched photons or QCD gauge configurations that include the
dynamics of QED in the sea.
