Abstract
We review the τ data-driven computation of Euclidean windows for the hadronic vacuum polarization contribution to the muon anomalous magnetic moment (aμ), which agree with the lattice results, making the difference of the e+e− data-driven methods with them more intriguing. This conundrum needs to be solved by next year, when the final FNAL aμ measurement will be published, in order to extract firm conclusions on possible new physics effects.

Report
Tau data based evaluation of dominant dipion contribution to hadronic vacuum polarization contribution to the anomalous magnetic moment of the muon are reviewed. The evaluation agrees with the lattice QCD computations, while electron-positron based results differ from both. Further work is needed to clarify this situation in light of the CMD-3 data, which is compatible with lattice and tau-based results.
