The Skyrme force parameters can be uniquely determined by coarse graining the Nucleon-Nucleon (NN) interactions at a characteristic momentum scale. We show how exact V-lowk potentials to second order in momenta are saturated with physical NN scattering threshold parameters at Center of Mass (CM) cut-off scales of about Lambda = 250 MeV for the S-waves and Lambda = 100 MeV for the P-waves. The pattern ofWigner and Serber symmetries unveiled previously and suggested by Quantum Chromodynamics (QCD) large N-c contracted symmetry emerges at these scales.
