Recent progress on isospin breaking corrections and their impact on the muon g-2 value

摘要：

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.
