Abstract
Using a chiral constituent quark approach based on the broken SU(6) \otimes O(3) symmetry, we focus on the spectroscopy of isospin-1/2 nucleonic resonances. A model for the eta photoproduction, embodying all known nucleonic resonances, shows clear need for a yet undiscovered S11 resonance, for which we determine the mass (1.730 GeV) and the total width (180 MeV).
