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.

Heatmaps for $$g_{q}=0.25$$ , $$g_{DM} = 1$$

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 $$g_{q}=0.5$$ , $$g_{DM} = 1$$
