abstract
We derive an analytic result for the pion pole contribution to the light-by-light scattering correction to the anomalous magnetic moment of the muon, $a_\mu = (g_\mu-2)/2$. Using the vector meson dominance model (VMD) for the pion transition form factor, we obtain $a_\mu^{{\rm LBL},\pi^0} = +56 \times 10^{-11}$.

Lepton $g-2$ non-universality of hadronic contributions and a sub-GeV window to New Physics
A rescaled difference a_μ-e of lepton g-2 values cancels short-distance effects and cuts hadronic vacuum polarization uncertainty by ~85%, offering a cleaner probe for sub-GeV new physics.

Field-theoretic versus data-driven evaluations of electromagnetic corrections to hadronic vacuum polarization in $(g-2)_\mu$
Virtual electromagnetic corrections largely cancel radiative-channel contributions in data-driven HVP evaluations for muon g-2, reconciling timelike and spacelike methods via a VMD model.
