We extract from the strong-coupling Hamiltonian lattice formulation of QCD a model for hadrons based on the use of quark and flux-tube degrees of freedom. The ordinary quark model of mesons and baryons is recovered as an appropriate limit, but the properties of hybrids, pure glue, and multiquark hadrons are also predicted by the model. The basic tenets of the model can be tested by lattice Monte Carlo simulations.
Isgur et al. (1985) studied this question.
