The use of simplified models as a tool for interpreting dark matter collider searches has become increasingly prevalent, and while early Run II results are beginning to appear, we look to see what further information can be extracted from the Run I dataset. We consider three ‘standard' simplified models that couple quarks to fermionic singlet dark matter: an s -channel vector mediator with vector or axial-vector couplings, and a t -channel scalar mediator. Upper limits on the couplings are calculated and compared across three alternate channels, namely mono-jet, mono- Z (leptonic) and mono- W/Z (hadronic). The strongest limits are observed in the mono-jet channel, however the computational simplicity and absence of significant t -channel model width effects in the mono-boson channels make these a straightforward and competitive alternative. We also include a comparison with relic density and direct detection constraints.
