Abstract
An Effective Field Theory for dark matter at a TeV-scale hadron collider should include contact interactions of dark matter with the partons, the Higgs and the Z. This note estimates the impact of including dark matter-Z interactions on the complementarity of spin dependent direct detection and LHC monojet searches for dark matter. The effect of the Z is small, because it interacts with quarks via small electroweak couplings, and the contact interaction self-consistency condition C/Λ2 < 4π/ŝ restricts the coupling to dark matter. In this note, the contact interactions between the Z and dark matter are parametrised by derivative operators; this is convenient at colliders because such interactions do not match onto low energy quark-dark matter contact interactions.
