Extended Data Fig. 6: Distributions of the VBF discriminants for nonresonant background.
From: Measurement of the Higgs boson width and evidence of its off-shell contributions to ZZ production
The distributions of the SM \({{{{{{\mathcal{D}}}}}}}_{2{{{{{\rm{jet}}}}}}}^{{{{{{\rm{VBF}}}}}}}\) (left) and \({{{{{{\mathcal{D}}}}}}}_{2{{{{{\rm{jet}}}}}}}^{{{{{{\rm{VBF}}}}}},\,a2}\) (right) kinematic VBF discriminants are shown in the 2ℓ2ν signal region, Nj≥2 category. The stacked histogram shows the predictions from simulation, which consists of nonresonant contributions from WW (green) and \({{{{{\rm{t}}}}}}\overline{{{{{{\rm{t}}}}}}}\) (gray) production, or other small components (orange). The black points with error bars as uncertainties at 68% CL show the prediction from the eμ CR data. While only the data is used in the final estimate of the nonresonant background, we note that predictions from simulation already agree well with the data estimate.
