Extended Data Fig. 7: Distributions of \({m}_{{{{{{\rm{T}}}}}}}^{{{{{{\rm{W}}}}}}{{{{{\rm{Z}}}}}}}\) in different Nj categories of the WZ control region.
From: Measurement of the Higgs boson width and evidence of its off-shell contributions to ZZ production
The postfit distributions of the transverse WZ invariant mass are displayed for the Nj = 0, Nj = 1, and Nj≥2 jet multiplicity categories of the WZ → 3ℓ1ν control region from left to right. Postfit refers to a combined 2ℓ2ν + 4ℓ fit, together with this control region, assuming SM H boson parameters. The stacked histogram is shown with the hashed band as the total postfit uncertainty at 68% CL. The color legend is given above the plots, with the different contributions referring to the WZ (light green), ZZ (blue), Z +jets (dark green), Zγ (yellow), \({{{{{\rm{t}}}}}}\overline{{{{{{\rm{t}}}}}}}\) (gray), and tV+X (brown, with X being any other particle) production processes, as well as the small EW ZZ production component (dark pink). The black points with error bars as uncertainties at 68% CL show the observed data. The middle panels along the vertical show the ratio of the data to the total prediction, and the lower panels show the predicted relative contributions of each process. The rightmost bins contain the overflow.
