Query: Perturbative S-matrix in discretized light cone quantization of
  two-dimensional \phi^4 theory   We study the S-matrix of two-dimensional \lambda\phi^4 theory in Discretized
Light Cone Quantization and show how the correct continuum limit is reached for
various processes in lowest order perturbation theory.
