Abstract
In this paper, we suggest how a constituent-quark description of hadrons may be obtained from a Hamiltonian lattice formulation of QCD. By treating the quark kinetic energy part of a lattice QCD Hamiltonian perturbatively, we extract an effective Hamiltonian for mesons in the space of qq¯ states to order 1/(ma. Although this approach can only strictly be justified for quarks heavy compared with the QCD scale, it may nonetheless provide a qualitatively reasonable picture of light quarks in hadrons.
