The proof of the decoupling theorem of quantum field theory given earlier [E. B. Manoukian, J. Math. Phys. 26, 1065 (1985)] in Minkowski space, in the distributional sense, for theories involving particles with vanishingly small masses as well is extended under more general conditions, thus being applicable to a larger class of graphs. All subtractions of renormalization are carried out at the origin of momentum space with the degree of divergence of a subtraction coinciding with the dimensionality of the corresponding subdiagram.
