Description
The three-loop calculation of the hadronic vacuum polarization in chiral perturbation theory, which I presented at the last Nordic Lattice Meeting, is now complete. I will demonstrate the full result, with particular attention given to the pieces that had not yet fallen into place last year. I will also show some first glimpses into the corresponding calculation in finite volume, which when complete will be a highly precise correction to lattice calculations.
