Nonperturbative Renormalization of Qed in Light-cone Quantization
نویسندگان
چکیده
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.

Nonperturbative renormalization and the electron’s anomalous moment in large-α QED
We study the physical electron in quantum electrodynamics expanded on the light-cone Fock space in order to address two problems: (1) the physics of the electron’s anomalous magnetic moment ae in nonperturbative QED, and (2) the practical problems of ultraviolet regularization and renormalization in truncated nonperturbative light-cone Hamiltonian theory. We present results for ae computed in a...
متن کاملNonperturbative Renormalization in Light - Cone Quantization ∗
Two approaches to nonperturbative renormalization are discussed for theories quantized on the light cone. One is tailored specifically to a calculation of the dressed-electron state in quantum electrodynamics, where an invariantmass cutoff is used as a regulator and a Tamm–Dancoff truncation is made to include no more than two photons. The other approach is based on Pauli– Villars regulators an...
متن کاملRenormalization in light–cone gauge: how to do it in a consistent way
We summarize several basic features concerning canonical equal time quantization and renormalization of Yang–Mills theories in light–cone gauge. We describe a “two component” formulation which is reminiscent of the light– cone hamiltonian perturbation rules. Finally we review the derivation of the one–loop Altarelli–Parisi densities, using the correct causal prescription on the “spurious” pole....

Using the pinch technique, we show how to construct the QCD effective charge to all orders. The extension of the concept of the renormalization-group-invariant and process-independent effective charge from QED to QCD is of special interest for several reasons. First, the existence of a QED-like effective charge, and the ability to identify directly and unambiguously the infinite subset of gluon...
متن کاملLight-cone Quantization of Quantum Chromodynamics*
We discuss the light-cone quantization of gauge theories from two perspectives: as a calculational tool for representing hadrons as QCD bound-states of relativistic quarks and gluons, and also as a novel method for simulating quantum field theory on a computer. The light-cone Fock state expansion of wavefunctions at fixed light cone time provides a precise definition of the parton model and a g...
