Masses of $[70,{\ell }^{+}]$ baryons in large $N_c$ QCD

Abstract

Previous work is extended from SU(2) to SU(3) and we present results for the mass spectrum of the $[70,{\ell }^{+}]$ ($\ell =0,2$) nonstrange and strange baryons in the $1/N_c$ expansion. We show that the dominant term is the spin-spin interaction and its contribution vanishes at large excitations.
