We derive limits on the interactions of dark matter with quarks from ATLAS null searches for jets+missing energy based on {approx}1 fb{sup -1} of integrated luminosity, using a model-insensitive effective theory framework. We find that the new limits from the LHC significantly extend limits previously derived from CDF data at the Tevatron. Translated into the parameter space of direct searches, these limits are particularly effective for {approx} GeV mass weakly interacting massive particles. Our limits indicate tension with isospin-violating models satisfying minimal flavor violation which attempt to reconcile the purported CoGeNT excess with Xenon-100, indicating that either a light mediator or nontrivial flavor structure for the dark sector is necessary for a viable reconciliation of CoGeNT with Xenon.

Benchmarks for dark matter searches at the LHC (2014, background): “This has motivated new and more model-independent strategies for DM searches at colliders, and led to a vast literature on the subject [1–88].”
Jet substructure at the Large Hadron Collider (2018, background): “Besides resonaces coupling to heavy SM particles, there exist predictions for resonances that couple to quarks and gluons [331–334], including simplified Dark Matter (DM) models in which resonances couple only to quarks and DM particles [335–337].”
On naturalness of the MSSM and NMSSM (2012, unknown): “[61–64].”
Beyond effective field theory for dark matter searches at the LHC (2013, background): “Although the dark matter leaves the detector without depositing energy, if it recoils against a final state parton, the resultant signature is a monojet recoiling against missing energy (MET) [1–9].”
On the validity of the effective field theory for dark matter searches at the LHC part III: analysis for the t-channel (2013, methodology): “J C A P 0 6 ( 2 0 1 4 ) 0 6 0 In order to avoid the overwhelming model-dependence introduced by the plethora of DM models discussed in the literature, DM searches at the LHC have made use of the Effective Field Theory (EFT) [18–28].”
Form factors for dark matter capture by the Sun in effective theories (2015, unknown): “Effective theory methods have proven to be a very powerful tool in the analysis of collider data [11–14], dark matter direct [15–23] and indirect [24–26] detection experiments, and in combined studies of these different strategies [27–29].”
Characterising dark matter searches at colliders and direct detection experiments: vector mediators (2014, unknown): “We also provide estimates for the projected limits from the LHC for 14 TeV operation after 30 fb − 1 , 300 fb − 1 and 3000 fb − 1 , and from LZ after a 10 ton year exposure (see ﬁgure 10).”
Recommendations on presenting LHC searches for missing transverse energy signals using simplified s-channel models of dark matter (2016, background): “In the limit of large Mmed, these (and all) models converge to a universal set of operators in an effective field theory (EFT) [13, 14, 26–29].”
