McKeon, G

A direct application of the Appelquist-Carazzone theorem while using mass-independent renormalization allows one to relate a Green's function calculated in a theory with massive particles with an analogous Green's function calculated in an effective theory in which there are no heavy particles present. This implies a relationship between the coupling constants and masses of the effective theory and those of the full theory. These ideas are presented in the context of a model in which SU(3) is broken down to SU(2) x U(1) by the presence of an octet of scalars. A discussion of the effective mass of the heavy vector particles is also given.
