Because the derivation of the constituent quark representation, from QCD remains an open, challenging problem, many models leading to chiral symmetry breaking have been proposed. An alternative to such models is presented which utilizes QCD sum rules. This QCD calculation is based on the observation that in a static chromoelectric background a light QCD quark resembles the light constituent quark in a heavy meson with the quantum number to the Qq pair. QCD sum rule techniques and the heavy quark effective theory are used to study the light quark energy and momentum distributions in the constituent quark. Results of QCD evolution will also be presented to show the effects of the perturbative gluon dressing of the light quark. Implications for the decays of a heavy meson will be discussed.
