Résumé

We discuss a perturbation theory on the light front regularized by a method analogous to Pauli–Villars regularization for the $(2{+}1)$-dimensional $SU(N)$-symmetric gauge theory. This allows constructing a correct renormalized light-front Hamiltonian.

Détail

Keywords: Pauli–Villars regularization, light-front quantization, gauge field theory.
