Phys. Rev. Lett. 73, 377–380 (1994)Is QCD Consistent with Quantum Field Theory?Received 4 March 1994; published in the issue dated 18 July 1994 The conventional treatment of QCD as a quantum field theory violates the requirement that the vacuum state must be unique. This apparent inconsistency is removed by establishing the incoherence of the degenerate states, a result similar to Borchers' result for a large class of theories (not including QCD) that they have many incoherent vacuum states. For QCD the physical vacuum state is set by a boundary condition. There are two possibilities, conventional QCD and an alternative that leads to new physical results. Thus the correct version can be identified by experiments. © 1994 The American Physical Society URL:
