  We analyze the potential dark matter implications of LHC events with missing
transverse momentum and a resonance, such as a Z', decaying to a pair of jets
or leptons. This final state contains significant discovery potential, but has
not yet been examined in detail by the LHC experiments. We introduce models of
Z' production in association with dark matter particles, propose reconstruction
and selection strategies, and estimate the sensitivity of the current LHC
dataset.
