    Nonperturbative Renormalization of QED in Light-Cone Quantization

    Get PDF
    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
