Hadronic structure on the light front. IV. Heavy and light baryons

This work is a continuation in our series of papers that addresses quark models of hadronic structure on the light front. The chief focus of this paper is the quantum-mechanical solution of the three-quark model Hamiltonian describing baryons. In Jacobi coordinates, we use a harmonic oscillator basis for the transverse directions. For the longitudinal momentum fractions xi, the pertinent basis follows from quantum mechanics in a "triangular cup"potential, which we solve exactly. We calculate the masses and light-front wave functions for the flavor symmetric 32+ baryons bbb, ccc, sss, uuu.
