  In "A Theory of Quantum Space-time" we constructed a form of field theory in
which Feynman diagrams describe real particle interactions, not virtual ones.
In this paper we outline a theory of discrete interactions based on hadron
field operators which bind quark in co- ordinate space, but not momentum space,
and offer explanations for the strong force, jets and Zweig's rule. As yet no
calculations have been carried out on the predictions of the theory, but we
indicate possibilities for testable predictions.
