Description

The leading uncertainty in obtaining precise fundamental information from particle physics experiments is often due to the difficulty of quantifying non-perturbative strong-interaction effects.

Over the last decade, Lattice QCD simulations, in which space and time are approximated by a discrete lattice of points, have improved in precision to the extent that a number of important quantities can be computed with a precision approaching, or even exceeding, 1%.

In order to make further progress in exploring the limits of the Standard Model and searching for new physics therefore, electromagnetic corrections must be included. This creates new theoretical challenges on the lattice associated with the long-range nature of the Coulomb interaction.

In this talk I will briefly review the status of lattice results for the hadronic inputs entering the amplitudes for weak decays of hadrons and motivate the need for including isospin-breaking corrections. I will then explain the theoretical framework I have been developing to include these radiative corrections and present numerical results.
