The quark model has been very successful in describing the spectroscopy of hadrons, both for light hadrons as well as for hadrons with heavy quarks. The spectroscopy of heavy baryons (or mesons) provides an interesting laboratory for understanding the theory of strong interactions, Quantum Chromodynamics (QCD), in a regime where perturbation calculations cannot be applied. In effective models of the heavy hadron systems, like heavy quark effective theory (HQET), the degrees of freedoms of the heavy quark are considered decoupled from those of the light quarks, so that a heavy baryon system can be modeled in a similar way as the helium atom is modeled.
