We propose a quark model description of the nucleon which includes, in a unified picture, valence quarks and a core of q~ pairs and gluons at the hadronic (non-perturbative) scale. The resulting parton distributions are evolved to high Q2 by means of an appropriate next-to-leading order evolution an
The mean field description of nuclear matter in the quark-meson coupling model is improved by the inclusion of exchange contributions (Fock terms). The inclusion of Fock terms allows us to explore the momentum dependence of meson-nucleon vertices and the role of pionic degrees of freedom in matter.
