Dr. Whitney has done work on the 3-body problem for theoretical baryon spectroscopy. The baryon is a hadron containing three quarks in some combination of up, down, strange, charm, and bottom. In determining the baryon energy spectrum, the baryon is treated as a three-body system with the interacting forces coming from a set of two-body potentials that depend on both the distance between the quarks and the spin and orbital angular momentum coupling terms. In particular, the Two-Body Dirac equations of constraint dynamics are such that they naturally account for spin through a Klein-Gordon-like equation obtained by squaring the Dirac equations.
