Colored Unparticles

We examine a scenario where the new physics at the LHC
includes an approximate conformal field theory, where some of the
degrees of freedom (aka "unparticles") carry a color charge. We
present a simple argument showing that the production cross section
for scalar unparticles mediated by a gauge interaction is given by
(2-d) times the standard particle expression, where d is the scaling
dimension of the unparticle field. We explicitly check that this is
indeed the case, which involves non trivial cancellations between
different Feynman diagrams, for the process q qbar to scalar
unparticles.
