Pruned jet mass distribution of the leading AK8 jet in the $0\ell$ (upper), $1\ell$ (middle), and $2\ell$ (lower) categories, and separately for the 1 (\cmsLeft) and 2 (\cmsRight) b-tagged subjet selections. The shaded band represents the uncertainty from the fit to data in the pruned jet mass sidebands. The observed data are indicated by black markers. The dashed vertical lines separate the lower (LSB) and upper (HSB) sidebands, the \PW and \Z bosons mass region (VR), and the signal region (SR). The bottom panels report the pulls in each bin, $(N^\text{data}-N^\text{bkg})/\sigma$, where $\sigma$ is the Poisson uncertainty in data. The error bars represent the normalized Poisson errors on the data.

Observed and expected 95\% CL upper limits on $\sigma(\PZpr) \, \B(\PZpr\to\Z\h) \, \B(\htobb)$ (\cmsLeft) and $\sigma(\PW') \, \B(\PW'\to\PW\h) \, \B(\htobb)$ (\cmsRight) as a function of the resonance mass for a single narrow spin-1 resonance, including all statistical and systematic uncertainties. The inner green and outer yellow bands represent the ${\pm}1$ and ${\pm}2$ standard deviation uncertainties on the expected limit. The red solid curve corresponds to the cross sections predicted by the HVT model~B with $\gV=3$.

Observed and expected 95\% CL upper limit with the ${\pm}1$ and ${\pm}2$ standard deviation uncertainty bands on $\sigma(\X) \, \B(\X\to\VH) \, \B(\htobb)$ in the HVT model~B benchmark scenario with $\gV=3$ as a function of the resonance mass, for the combination of all the considered channels.

Observed exclusion in the HVT parameter plane $\left[ \gV \cH, \ g^2 \cF / \gV \right]$ for three different resonance masses (1.5, 2.0, and 2.5\TeV). The parameter $\gV$ represents the coupling strength of the new interaction, $\cH$ the coupling between the HVT bosons and the Higgs boson and longitudinally polarized SM vector bosons, and $\cF$ the coupling between the heavy vector bosons and the SM fermions. The benchmark scenario~B with $\gV=3$ is represented by the red point. The gray shaded area corresponds to the region where the resonance natural width is predicted to be larger than the typical experimental resolution (5\%), and thus the narrow-width approximation breaks down.
