Nuclear forces and currents in large-N C QCD

  • D. O. RiskaEmail author


Expression of the nucleon-nucleon interaction to leading order in 1/N C in terms of Fermi invariants allows a dynamical interpretation of the interaction and a consistent construction of the associated interaction currents. The numerically significant components of 4 different modern realistic phenomenological interaction models admit very similar meson exchange interpretations in the large-N C limit. The ratio of the volume integrals of the leading, next-to-leading and next-to-next leading-order terms in these interaction models is roughly \(300: 5\mbox{--}10: 0.1\), which corresponds fairly well to the ratios of 1/N C 2 between the terms that would be suggested by the 1/N C expansion if N C = 3.
