ATLAS Dijets: Simulated signals for a sample of mediator masses are shown, superimosed on the double-differential dijet cross section in the most central rapidity region, binned by dijet mass, as measured by ATLAS at 7 TeV [9]. The upper plot compares the measured cross section to the model expectation, and the lower plot shows the perturbation in the ration compared to the relative uncertainty in the measurement. The signals form a 1D parameter space scan in mediator mass for fixed dark matter mass and mediator couplings; \({{M_{\rm DM}}}=600\) GeV, \({{g_{q}}}=0.375\) and \({{g_{\rm DM}}}= 1\). These data were used in the original Contur paper. See here.

Simulated signals for a sample of mediator masses are shown, superimosed on the double differential dijet cross section in the most central rapidity region, binned by leading jet \(p_{\rm T}\)and rapidity as measured by CMS at 7 TeV [30]. The upper plot compares the measured cross section to the model expectation, and the lower plot shows the perturbation in the ration compared to the relative uncertainty in the measurement. The signals form a 1D parameter space scan in mediator mass for fixed dark matter mass and mediator couplings; \({{M_{\rm DM}}}=600\) GeV, \({{g_{q}}}=0.375\) and \({{g_{\rm DM}}}= 1\).|

Simulated signals for a sample of mediator masses, superimposed on the differential cross section for the \(W+\geq2\) jet process, binned in the mass of the dijet pair as measured by ATLAS at 7 TeV [15]. The signals form a 1D parameter space scan in mediator mass for fixed dark matter mass and mediator couplings; \({{M_{\rm DM}}}=600\) GeV, \({{g_{q}}}=0.375\) and \({{g_{\rm DM}}}= 1\). This illustrates the sensitivity of vector-boson-plus-jet (\(V+\)jet) measurements to this model, in this case the dijet mass differential cross section in \(W+\)-jet events. Strictly speaking, the measurement is made for events with a single charged lepton, \(E_T^{\rm miss}\), and jets, interpreted as \(W\)+jets in the SM. In the BSM model considered here, \(E_T^{\rm miss}\)could in principle also arise from the dark matter candidate. However, inspections shows that the sensitivity, which is at mediator masses below around a TeV or so, arises from genuine \(W\) bosons produced in association with the mediator which is not a signature typically considered in constraints on this class of model.

Simulated signals for a sample of mediator masses, interpreted as perturbations to the \(ZZ\rightarrow l^+l^- {{E_T^{\rm miss}}}\) cross section corresponding to the data as measured by ATLAS at 7 TeV [4]. The signals form a 1D parameter space scan in mediator mass \(M_{Z^{\prime}}\)for fixed dark matter mass and mediator couplings; \({{M_{\rm DM}}}=100\) GeV, \(g_{q}=0.375\) and \(g_{\rm DM} = 1\). This is a fiducial cross section measurement of \(pp \rightarrow l^+l^- + {{E_T^{\rm miss}}}\), interpreted in the paper as \(pp \rightarrow ZZ \rightarrow l^+l^- \nu \bar{\nu}\), but performed in a sufficiently model-independent fashion that it has the same sensitivity to the \(l^+l^- +\) dark matter channel. The production diagrams are the same as the \(V\)-jets case, but in this case the mediator decays to dark matter rather than back to quarks.
