Exactly renormalizable model in quantum field theory III. Renormalization in the case of two V-particles

Abstract

A simpler formulation of the renormalized Schrödinger equation is given for the model discussed previously 1). The renormalization is extended to the case of more than one heavy particle. The final results contain no divergentes and are easily visualized in terms of diagrams which are calculated using only the renormalized coupling constants. It is conceivable that this formulation of the theory also applies to more realistic models.
