Nonperturbative Renormalization of QED in Light-Cone Quantization
As a precursor to work on QCD, we study the dressed electron in QED
nonperturbatively. The calculational scheme uses an invariant mass cutoff,
discretized light-cone quantization, a Tamm--Dancoff truncation of the Fock
space, and a small photon mass. Nonperturbative renormalization of the coupling
and electron mass is developed.Comment: Latex, 4 pages, 1 figur
