Resumo

© Owned by the authors, published by EDP Sciences, 2010.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 cutoffthrough the SRG transformation.
