Observed and expected 95% CL upper limits with the $\pm 1$ and $\pm 2$ standard deviation uncertainty bands on the product $\mathit{\sigma }(\mathrm{X})\mathcal{B}(\mathrm{X}\to \mathrm{V}\mathrm{H})\mathcal{B}(\mathrm{H}\to \mathrm{b}\overline{\mathrm{b}})$ in the combined heavy vector triplet hypothesis, for the combination of the eight categories. The purple and red solid curves correspond to the cross sections predicted by the HVT model A and model B, respectively
