Abstract
Lattice determinations of the Standard Model expectation for the leading order hadronic vacuum polarization contribution to the anomalous magnetic moment of the muon are now sufficiently precise that further progress requires the inclusion of contributions from strong and electromagnetic isospin-breaking effects. We provide a continuum, SU(3) chiral perturbation theory based estimate of the former, using flavor-breaking hadronic tau decay sum rules to determine a crucial input higher-order low-energy constant. Implications of the form of this result are also discussed.
