  We perform a detailed study of the dark Z' portal using a generic
parametrization of the Z'-quarks couplings, both for light (8-15)GeV and heavy
(130-1000)GeV dark matter scenarios. We present a comprehensive study of the
collider phenomenology including jet clustering, hadronization, and detector
artifacts, which allows us to derive accurate bounds from the search for new
resonances in dijet events and from mono-jet events in the LHC 7TeV, LHC 8TeV,
and Tevatron 1.96 TeV data. We also compute the dark matter relic abundance,
the relevant scattering cross sections and pair-annihilation spectrum, and
compare our results with the current PLANCK, Fermi-LAT and XENON100/LUX bounds.
Lastly, we highlight the importance of complementary searches for dark matter,
and outline the excluded versus still viable parameter space regions of the
dark Z' portal.
