Tau data-based evaluations of the hadronic vacuum polarization contribution to the muon g-2

We review the \tau τ data-driven computation of Euclidean windows for the hadronic vacuum polarization contribution to the muon anomalous magnetic moment ( a_\mu a μ ), which agree with the lattice results, making the difference of the e^+e^- e + e − data-driven methods with them more intriguing.

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