Quantum electrodynamics as a supersymmetric theory of loops
Journal Article

It is shown that the Wilson loop is not a renormalizable operator even in free QED. A modification is suggested and proven to be renormalizable. Feynman's worldline formulation of QED is generalized to include spinning particles and matter loops, using this modified Wilson loop. QED formulated this way is shown to have a supersymmetry. A superfield formalism is found that describes it. QED is rewritten as a second quantized field theory of loop functionals. copyright 1987 Academic Press, Inc.
