Description

Lattice QCD calculations for many quantities have now reached
sub-percent precision so that isospin-breaking corrections, including
QED effects, must be included to fully exploit this precision in
determining these quantities. Here, we present a theoretical
framework, based on the infinite-volume reconstruction (IVR), for
calculating electromagnetic corrections to finite-volume lattice QCD
calculations. In this method, the hadronic correlation functions are
first processed theoretically in infinite volume, in such a way that
the required matrix elements can be determined non-perturbatively from
lattice QCD calculations with finite-volume uncertainties which are
exponentially small in the volume.
