  Jurco, Moller, Schraml, Schupp, and Wess have shown how to construct
noncommutative SU(N) gauge theories from a consistency relation. Within this
framework, we present the Feynman rules for noncommutative QCD and compute
explicitly the most dangerous Lorentz-violating operator generated through
radiative corrections. We find that interesting effects appear at the one-loop
level, in contrast to conventional noncommutative U(N) gauge theories, leading
to a stringent bound. Our results are consistent with others appearing recently
in the literature that suggest collider limits are not competitive with
low-energy tests of Lorentz violation for bounding the scale of spacetime
noncommutativity.
