Abstract: (Elsevier)

We show explicitly, to the two-loop level, that the decoupling theorem of Appelquist and Carazzone is valid, and a consistent light effective field theory exists, for quantum electrodynamics in arbitrary α-gauges, and non-abelian gauge theory in α = 0, Landau gauge, renormalized by minimal subtraction.
