Negative parity nonstrange baryons in large Nc QCD: quark excitation versus meson-nucleon scattering

We show that the two complementary pictures of large $N_c$ baryons - the single-quark orbital excitation about a symmetric core and the meson-nucleon resonance -- are compatible for $ell$ = 3 SU(4) baryons. The proof is based on a simple Hamiltonian including operators up to order $mathcal{O}(N^0_c)$ used previously in the literature for $ell$ = 1.
