Excited $[70,{\ell }^{+}]$ baryon resonances in large $N_c$ QCD

Abstract

We summarize results obtained in the $1/N_c$ expansion method for the masses of baryon resonances belonging to the $[70,{\ell }^{+}]$ multiplet. They represent an extension of our previous studies from two to three flavors. A better approach to mixed symmetric states of any angular momentum and parity is also outlined.
