Description
Fermilab has measured muon $g-2$ to unprecedented precision. The central value agrees with the previous BNL measurement. On the theory side, the main source of uncertainties are from the two hadronic contributions -- hadronic vacuum polarization (HVP) and hadronic light-by-light scattering (HLbL). Recent lattice QCD calculations have made a lot of contributions in determining these two contributions. These also lead to a significant shift in the theoretical value of the HVP contribution, which brings the final theoretical prediction of muon $g-2$ much closer the experimental measurement. In this talk, I will review these lattice QCD calculations of the hadronic contribution to muon $g-2$.
