abstract = {The low, euclidean momentum behavior of the hadron vacuum
polarization (HVP) is critical for determining, amongst
other quantities, the anomalous magnetic moments of the
muon. Here we present lattice QCD results for the first two
derivatives of the HVP function at vanishing virtuality [1].
Computations are performed with 2 + 1 + 1 flavors of
staggered quarks around the physical mass point, in volumes
of linear extent larger than 6 fm, and at six values of the
lattice spacing, allowing for a fully controlled continuum
extrapolation. We further consider possible uncertainties
which stem from finite-volume and isospin-breaking effects.
After adding to our connected contributions the disconnected
terms presented in [2], we compare the resulting derivatives
of the full HVP with phenomenological estimates.},
