The role of intermediate $\hat{I}”\hat{I}”$ states in nucleon-nucleon scattering in the large-$N_c$ and unitary limits, and $\hat{I}”\hat{I}”$ and $\hat{I}\text{c◯}\hat{I}\text{c◯}$ scattering

We explore potential explanations for why using large-$N_c$ ($N_c$ is the number of colors) scaling to determine the relative size of few-nucleon low-energy operators agrees with e…
