• All baryon resonances can be systematized from one and the same point of view, according to what they would look like if the number of colors N_c was large. Although in the real world N_c is only three, the consequences of the large-N_c classification are visible in the observed spectrum. At large N_c baryon resonances are collective excitations about intrinsic one-quark or particle-hole states in a certain mean field. Exotic pentaquark baryons appear as 'Gamov-Teller' particle-hole excitations. A charmed B_c pentaquark baryon is predicted which may well be so light that it is stable with respect to strong decays.
