Description
The Muon g-2 Experiment that just commenced running at Fermilab intends to probe the present 3-sigma tension between theory and experiment by reducing the experimental uncertainty by a factor of four. In order, however, to determine definitively whether any future observed deviation is due to new physics, the Standard-Model theory error must be brought to the same level of precision. Lattice QCD provides the only first-principles approach for calculating the hadronic contributions to the muon g-2, which are the dominant sources of error in the Standard-Model value. I review recent progress on lattice-QCD calculations of the hadronic contributions to the muon g-2, and also discuss future plans and prospects for reducing the theory error to the level of the Muon g-2 and planned J-PARC experiments.
