Abstract

The inclusion of electromagnetic effects in unquenched QCD can be accomplished using ensembles generated in dynamical simulations with pure QCD provided the change in the quark determinant induced by a weak electromagnetic field can be efficiently computed. A stochastic technique for achieving this in the case of dynamical domain wall calculations is described.
