Query: Mass Relations for the Quark-Diquark Model   Quark model with potentials derived from QCD, including the quark-diquark
model for excited hadrons gives mass formulae in very good agreement with
experiment and goes a long way in explaining the approximate symmetries and
supersymmetries of the hadronic spectrum, including the symmetry breaking
mechanism.
