  None of the asymptotic states commonly used in perturbative QCD are gauge
invariant. A similar statement could be made about QED, but in QED one can
construct gauge invariant "dressed" states (with Dirac electrons) that are
unitarily equivalent to the states used in perturbation theory. Perturbative
expansions of dressed states have been derived for QCD, but Gribov copies
obstruct these states from remaining gauge invariant non-perturbatively.
Introduced here are new QCD states that are exact solutions to the Dirac
condition, so they remain gauge invariant non-perturbatively. The quark content
of these states is restricted to be meson-like, baryon-like, or
anti-baryon-like locally at each point of space. The states differ from others
previously presented due to the use of creation operators defined in coordinate
space rather than in momentum space.
