Description
Toward a complete sub-percent lattice determination of the muon g-2
We present an update on the Fermilab Lattice, HPQCD, and MILC collaboration's ongoing effort to compute the leading- and next-to-leading-order hadronic vacuum polarization (HVP) contributions to the muon anomalous magnetic moment. We report preliminary results for the long-distance disconnected and I=0 contributions obtained using a new dataset at a lattice spacing of 0.057 fm. We also discuss plans to update the dominant light-quark connected contribution with increased statistics and additional scale-setting schemes. A companion talk will present the status of the isospin-breaking calculation. All calculations are performed on 2+1+1 flavor HISQ ensembles with a physical pion mass.
