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 ahad,LOμ when using τ lepton data.When these corrections are applied to the new combined data on the π±π0 spectral function,the prediction for abad,LOμ based on τ lepton data gets closer to the one obtained using e+e-data.
