• The mass spectra of nucleon resonances with spin 1/2, 3/2, and 5/2 are systematically studied in a constituent quark model with meson-quark coupling, which is inspired by the spontaneous breaking of chiral symmetry of QCD. Meson-quark coupling gives rise not only to the one-meson-exchange potential between quarks but also to the self-energy of baryon resonances, owing to the existence of meson-baryon decay channels. These two contributions are consistently taken into account in the present model. The gross properties of nucleon resonance spectra are reproduced fairly well, although the predicted mass of N(1440) is too lar e.
