Description
We present a complete calculation of the hadronic vacuum polarization contribution to the muon magnetic anomaly reaching the sub-5‰ precision level. Our result, recently published in Nature, constitues an unprecedented validation of the Standard Model, at the given accuracy, in explaining the experimental measurement world average of $a_\mu$, agreeing with the latter at 0.5 standard deviations.
Several intermediate quantities used as benchmarks for lattice calculations, the so-called Euclidean time-distance windows, will be addressed in the talk.
