Abstract
A QCD model is defined to study questions of quark and gluon parton saturation at small x-values. The model uses a source consisting of a nucleus of heavy quarkonium bound states, states well understood in QCD. Deeply inelastic scattering, using the currents j(x) = − 1 4 F μν aF μν a and j μ(x) = ψγ μψ , is evaluated in Born and one-loop approximation in order to extract quark and gluon distributions. Quark distributions are observed to saturate while gluon distributions have a saturating and a nonsaturating component.
