Causal scattering matrix in quantum electrodynamics
arXiv:1209.6313
Abstract
A causal scattering matrix of quantum electrodynamics is constructed by means of chronological product of Lagrangians where the fields have the different arguments. This scattering matrix is a convergent series and does not contain the diverging integrals.
