Abstract:
We describe some recent results on isospin breaking corrections which are of relevance for predictions of the leading order hadronic contribution to the muon
anomalous magnetic moment aμhadLO when using τ lepton data. When these corrections are applied to the new combined data on the π±π0 spectral function, the prediction for aμhadLO based on τ lepton data gets closer to the one obtained using e+e- data.
