Infrared convergence of Feynman integrals for the masslessA4-model

  • J. H. Lowenstein
  • W. Zimmermann


For the masslessA4-model it is proved that renormalization can be formulated such that each Feynman diagram yields an ultraviolet and infrared convergent contribution to the Green's functions.
