read the original abstract
Strassler's formulation of the string-derived Bern-Kosower formalism is extended to consider QED processes in homogeneous constant external field. A compact expression for the contribution of the one-loop with arbitrary number of external photon lines is given for scalar QED. Extension to spinor QED is shortly discussed.

Worldline representation of multiloop amplitudes in quantum electrodynamics
Worldline master integrals combine whole classes of QED Feynman diagrams and yield new coefficients for the two-loop scalar QED vacuum polarization.

Worldline Modeling of Ultra-Intense Lasers for N-photon Scattering Processes
Compact worldline 'master formulae' for arbitrary-N photon scattering in strong-field backgrounds are presented, but the derivations are largely deferred to the authors' own prior and companion papers.
