    "abstract": "A gauge-invariant formalism is presented for the practical treatment of\nphoto- and electroproduction of pseudoscalar mesons off nucleons that allows an\nexplicit incorporation of hadronic final-state interactions. The\nsemi-phenomenological approach is based on a field theory developed by one of\nthe authors. It generalizes an earlier approach by allowing for systematic\nimprovement of approximations in a controlled manner. The practical feasibility\nis illustrated by applying the lowest-order result to the photoproduction of\nboth neutral and charged pions.",
