abstract = {The anomalous magnetic moment of the muon, as a low energy
precision observable, has long served as a test of the
Standard Model (SM) of particle physics. The latest muon $g
- 2$ measurements at Fermilab confirm the previous BNL
result, hence emphasizing, up to 5.1 standard deviations,
the discrepancy between the experimental world average value
and the reference SM prediction. The uncertainty of the
latter is dominated by the hadronic vacuum polarisation
(HVP) contribution, which is traditionally evaluated using
dispersion integrals and experimental hadronic cross section
data. However, recent independent HVP evaluations based on
lattice QCD calculations and on a new measurement of the
$e^+e^- \to \pi^+\pi^-$ cross section are providing hints
for a significantly reduced tension with the direct
experimental determination. In this invited talk, after
briefly reviewing the status of lattice calculations in the
field, we present the new result from first principles by
the BMW Collaboration at the remarkable precision of 0.32
ppm, with a particular focus on our evolving understanding
of the HVP contribution and implications for indirect
searches of new physics.},
