Nucleon resonances are thought to play a decisive role in reactions of strong, electromagnetic and weak probes on nucleons. The extent to which nucleon resonances determine both unpolarized and polarized observables remains an open question in the second and third resonance regions from center-of- mass (COM) energies, E in the range 1.4 GeV = E = 2.0 GeV. A model determination of the T matrix consistent with the observed meson production data in this kinematic regime seeks to resolve the resonance structure of the nucleon. The determination of the resonance spectrum will yield insight into fundamental aspects of quantum chromodynamics, such as confinement.
