Heatmaps for three-generation Vector DM model 2017/9/21

The sensitivities derived from multiple distributions such as those discussed in the previous section are combined into heatmaps’ which delineate exclusion regions and contours in the parameter space of \(M_{\rm DM}\)and \(M_{Z^{\prime}}\).

Heatmaps displaying 2D parameter space scans in mass in planes corresponding to a fixed \(g_{\rm DM}=1\) and variable \(g_{q}\). The confidence level of exclusion represented corresponds to testing the full signal strength hypothesis against the null background-only hypothesis. The combination of measurements entering into the confidence level presented here is the maximally sensitive allowed grouping, considering all available measurements.

To see where the sensitivity comes from, here’s what we have from the inclusive, dijet and multijet measurements:

this is the exclusion from the W+jet and Z+jet and Drell-Yan measurements. Top quark measurements also contribute here:

and here’s what the various diboson measurements do.

The photon measurements (inclusive, photon+jet, diphoton) don’t add anything significant for this model.

And higher coupling: Heatmaps for \(g_{q}=0.5\) , \(g_{DM} = 1\)
