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.

Report
Strong isospin-breaking contributions to the leading order hadronic vacuum polarization part of the anomalous magnetic moment of the muon are studied. A continuum, SU(3) chiral perturbation theory based estimate is obtained from flavor breaking inverse-moment finite-energy sum rule analysis of hadronic τ decay data. This result dominated by resonance region contributions agrees within errors with the only full lattice result obtained by summing the connected and disconnected contributions.
The scientific content of the contribution is very high. Minor revision is requested.

(in reply to Report 1 by Swagato Banerjee on 2024-11-29)The requests for revision just involve fixing typos (missing comma, missing square root sign
and 1 mis-spelling. I confirm that these changes can be made and assume there is no need
to resubmit a file with only such changes made -- rather they can be implemented by
the journal, with my permission
