Abstract
A perturbative expansion for QED and QCD bound states is formulated in gauge. The constituents of each Fock state are bound by their instantaneous interaction. In QCD an O() confining potential arises from a homogeneous solution of Gauss' constraint. The potential is uniquely determined by the QCD action, up to a universal scale. The Cornell potential is reproduced for quarkonia, and corresponding ones found for higher Fock states, baryons and glueballs.
