| Abstract: | Poincaré-covariant quark models of the nucleon, the resonance and their excitations are explored. The baryon states are represented by eigenfunctions of the four-velocity and
a confining mass operator, which reproduces the empirical baryon masses up to 1700 MeV to an accuracy of . Models of constituent-quark currents provide the relations between ground-state properties and transition amplitudes.
