Description
The overall accuracy of the Standard Model prediction of the anomalous
magnetic moment of the muon is currently limited by hadronic
effects. I review the status of lattice QCD calculations, aimed at
providing precise estimates for the hadronic vacuum polarisation and
hadronic light-by-light scattering contributions, respectively. In the
case of the leading hadronic vacuum polarisation contribution I will
focus on systematic effects in current lattice simulations and outline
the progress made in computing the contributions from
quark-disconnected diagrams. For the hadronic light-by-light
scattering contribution the different computational and conceptual
strategies employed by various groups will be reviewed.
