Description
Lattice QCD calculations are beginning to push comparisons between theoretical and experimental tests of the Standard Model to unprecedented precisions. In order to meet this precision goal, QED effects must be introduced. In this talk, I will present a systematic study of the spectra of hadrons using a novel technique in which power-law finite-volume effects are mitigated through the introduction of a non-zero photon mass. I will show that the effects of zero-mode and other non-perturbative contributions may be fully accounted for within this framework, and explore an isospin breaking scheme in which electromagnetic and strong isospin breaking effects are separated at leading order.
