The large $N_c$ nuclear potential puzzle arose because three- andhigher-meson exchange contributions to the nucleon-nucleon potential did notautomatically yield cancellations that make these contributions consistent withthe general large $N_c$ scaling rules for the potential. Here it is proposedthat the resolution to this puzzle is that the scaling rules only apply forenergy-independent potentials while all of the cases with apparentinconsistencies were for energy-dependent potentials. It is shown explicitlyhow energy-dependent potentials can have radically different large N behaviorthan an equivalent energy-independent one. One class of three-meson graphs iscomputed in which the contribution to the energy-independent potential isconsistent with the general large N rules even though the energy-dependentpotential is not.Comment: Corrections to the toy mode
