Description
We investigate finite volume effects in the hadronic vacuum polarization,
with an eye toward the corresponding systematic error in the muon
anomalous magnetic moment. While it is well known that leading-order
chiral perturbation theory does not provide a good description of the
hadronic vacuum polarization, it turns out that it gives a much better
representation of finite volume effects. Indications are that finite
volume effects cannot be ignored when the aim is a few percent level
accuracy for the hadronic contribution to the muon anomalous magnetic
moment, even when $m_\pi L \sim 4$ and $m_\pi \sim 200$ MeV.
