The baryon states are represented by eigenfunctions of the four-velocity and a confining mass operator, which reproduces the empirical spectrum up to $\\sim$ 1700 MeV to an accuracy of $\\sim 6%$. Models of constituent quark currents provide the relations between ground-state properties and transition amplitudes.","authors_text":"D. O. Riska, F.
