Ultraviolet finiteness of Chiral Perturbation Theory for two-dimensional Quantum Electrodynamics
S. A. Paston, E. V. Prokhvatilov, V. A. Franke
We consider the perturbation theory in the fermion mass (chiral perturbation theory) for the two-dimensional quantum electrodynamics. With this aim, we rewrite the theory in the eq…
Gauge Invariant Regularization of Quantum Field Theory on the Light-Front
S. A. Paston, E. V. Prokhvatilov, V. A. Franke
Gauge invariant regularization of quantum field theory in the framework of Light-Front (LF) Hamiltonian formalism via introducing a lattice in transverse coordinates and imposing b…
The Light-Front Hamiltonian formalism for two-dimensional Quantum Electrodynamics equivalent to the Lorentz-covariant approach
S. A. Paston, E. V. Prokhvatilov, V. A. Franke
A light-front Hamiltonian reproducing the results of two-dimensional quantum electrodynamics in the Lorentz coordinates is constructed using the bosonization procedure and an analy…
