Extension of Renormalizability

High Energy Physics - Phenomenology 2007-05-23 v1

Abstract

Arguments are provided which show that extension of renormalizability in quantum field theory is possible. A dressed scheme for the perturbation expansion is proposed. It is proven that in this scheme a nonrenormalizable interaction becomes renormalizable in the restrictive sense, i.e. its ultraviolet divergences can be cancelled by a finite number of counterterms included in the Lagrangian. As an illustration, the renormalization of the π\pi-nucleon pseudovector interaction is discussed in some detail.
