Tau Data-Based Evaluations of the hadronic vacuum polarization contribution to the muon g-2
Abstract
We review the tau data-driven computation of Euclidean windows for the hadronic vacuum polarization contribution to the muon anomalous magnetic moment (amu), 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 amu measurement will be published, in order to extract firm conclusions on possible new physics effects.
