摘要：We calculate the leading isospin-violating and electromagnetic corrections for
the decay − ! 0− at low energies. The corrections are small but relevant for the
inclusion of decay data in the determination of hadronic vacuum polarization especially
for the anomalous magnetic moment of the muon. This contribution is based on Ref.
