Description
Non-perturbative effects in precision calculations involving QCD at low energies must be handled with tools such as lattice and effective field theory. The achievable level of precision in many modern experiments demands that electromagnetic effects in addition to QCD be included in theoretical calculations. In lattice QCD where simulations are performed in non-physical Euclidean spacetimes of finite volume, this necessitates the introduction of dedicated finite-volume QED prescriptions. In this talk I will discuss different prescriptions, the complications arising in extracting physical information from lattice simulations and the impact for future precision tests in the search for new physics.
