Low Scale Saturation of Effective NN Interactions and Their Symmetries Ruiz Arriola, Enrique Effective NN interactions Renormalization group Skyrme forces Wigner and Serber symmetry 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 Vlowk potentials to second order in momenta are saturated with physical NN scattering threshold parameters at Center of Mass (CM) cut-off scales of about Λ=250MeV for the S-waves and Λ=100MeV for the P-waves. The pattern of Wigner and Serber symmetries unveiled previously and suggested by Quantum Chromodynamics (QCD) large Nc contracted symmetry emerges at these scales. 2017-02-22T12:16:29Z 2017-02-22T12:16:29Z 2016 info:eu-repo/semantics/article Ruiz Arriola, E.
