We apply the similarity renormalization group (SRG) approach to evolve a nucleon-nucleon (N N) interaction in leading-order (LO) chiral eﬀective ﬁeld theory (ChEFT), renormalized within the framework of the subtracted kernel method (SKM). We derive a ﬁxed-point interaction and show the renormalization group (RG) invariance in the SKM approach. We also compare the evolution of N N potentials with the subtraction scale through a SKM RG equation in the form of a non-relativistic Callan-Symanzik (NRCS) equation and the evolution with the similarity cutoﬀ through the SRG transformation.
