In this work we apply the similarity renormalization group (SRG) approach to evolve an effective nucleon–nucleon (NN) potential in leading-order (LO) chiral effective field theory (ChEFT). We present the results obtained for a NN potential in the 1S0 channel derived within the framework of the subtracted kernel method (SKM).

In this work we study the similarity renormalization group (SRG) evolution of chiral effective field theory (ChEFT) nucleon-nucleon (NN) interactions derived within the framework of the subtracted kernel method (SKM) approach. We apply the SRG transformation to evolve the leading-order (LO) ChEFT NN potential in the 1S0 and the 3S1-3D1 partial-wave channels and calculate the corresponding phase-shifts.
