Abstract
Field theories of quarks (QCD) have been found to be difficult to handle. A major component of the trouble is the confining nature of strong interactions. Hence, it is proposed that the confinement of quarks in hadrons be treated as a direct interaction. But scattering interactions between hadrons can still be via fields. This requires that the total hadron wave function with directly interacting component quarks be second-quantized. A simple case of spin-zero quarks is described before the discussion of spin-half quarks. Such a theory is ideal for hadron phenomenology. But there is also a possibility that it might develop into a more fundamental theory. In that case it could improve the understanding of the existing theory of QCD.
