OUTP-12-05P LHC and Tevatron bounds on the dark matter direct detection cross-section for vector mediators

We study the interactions of a new spin-1 mediator that connects the Stan-dard Model to dark matter. We constrain its decay channels using monojet and monophoton searches, as well as searches for resonances in dijet, dilepton and diboson final states including those involving a possible Higgs. We then interpret the resulting limits as bounds on the cross-section for dark matter direct detec-tion without the need to specify a particular model. For mediator masses between 300 and 1000 GeV these bounds are considerably stronger than the ones obtained under the assumption that the mediator can be integrated out. ar X i
