摘要：We discuss the implementation of Light Cone Field Theory (LCFT) in the causal Bogoliubov-
Epstein-Glaser finite S-matrix formulation. The benefits result from the simple vacuum structure
of LCFT which make possible calculations of the S-matrix in a perturbative-like manner even in
the presence of a nontrivial, nonperturbative vacuum.The interdependence of particle and vacuum
properties leads to an iterative scheme for the determination of the vacuum part of the Hamiltonian.
