Resumen:
Starting from QCD and applying several approximations, like restricting to SU(2) for color, a system of quarks in more than one orbital are considered, Restricting to quarks in the lowest s-orbit results in an analytic solution. We give a recursive method how to include all orbitals and only restrict to s- and p-orbitals. The structure of the Hamiltonian is discussed. Under certain approximations for the potential interaction, all analytic result is obtained. We discuss possible methods to treat the problem and explain the state of the investigation.
