Distribution of the fourlepton reconstructed mass in full analysis mass range with a requirement on the MELA discriminant D_{gg} > 0.65 to reject the ZZ background for the sum of the 4e, 4μ, and 2e2μ channels.

Distribution of the fourlepton reconstructed mass in full analysis mass range with a requirement on the MELA discriminant D_{gg} < 0.5 to reject the gg+VV→ZZ signal for the sum of the 4e, 4μ, and 2e2μ channels. Points represent the data, shaded histograms represent the background and dottedshaded histogram the gg+VV→ZZ expectations. The expected distributions are presented as stacked histograms.

Distribution of the expected fourlepton reconstructed mass in full analysis mass range for the sum of the 4e, 4μ, and 2e2μ channels and for gg+VV→ZZ processes. The expected distribution for a scenario corresponding to a scaling of the width by 25 together with mu=1 is also shown. This illustrates the expected change in gg+VV→ZZ production when changing the Higgs width and at the same time constraining the peak cross section to the SM expectation. 

Distribution of the generated fourlepton crosssection in mass range [100, 500] GeV for the gg→ZZ2e2μ channel with different couplings and width scaling. Under a scaling of the width only, the peak yield decreases by the scaling factor while the high mass part of the distribution stays unchanged. When scaling both the width and the coupling product squared, the yield in the peak is kept unchanged while an increase of the yield in the offshell region by this scaling factor is expected.

Distribution of the MELA discriminant D_{gg} in [220330] GeV mass range to reject the gg+VV→ZZ signal for the sum of the 4e, 4μ, and 2e2μ channels. Points represent the data, shaded histograms represent the background and dottedshaded histogram the gg+VV→ZZ expectations. The expected distributions are presented as stacked histograms.

Expected and observed number of events for m_{4l} > 220 GeV per channel and for the sum of the 4e, 4μ and 2e2μ channels. The numbers for the gg signal and the total gg contribution are given for μ=1 (SM). The column ``signal enriched'' has instead cuts of m_{4l} > 330 GeV and D_{gg} > 0.65. The numbers correspond to 8 TeV data only. VBF errors are negligible with respect to the corresponding gg sources, so they are not reported.

Figure  Description  

Yields variation with respect to the SM r=1 senario for each component entering the signal model. The absolute variation of each component and of the total expectations is shown for the gluongluon (left) and VBF (right) production modes. 
Event yields expected for the different signal components after baseline selection assuming r = 1.
Event yields expected for background processes and observed data. Statistical uncertainties are shown for all backgrounds. The systematic uncertainty is shown for backgrounds derived from data. Processes which correspond with < 0.1% to the total event yields expected are omitted for simplicity.
Event yields in a signalenriched region expected for the signal and background processes and observed in the data for the ee and μμ channels. The abbreviation gg is used to denote the process gg→ZZ→2l2ν. The abbreviation VBF is used to denote the process qq→ZZqq→2l2νqq. The signalenriched region is defined by E_{T}^{miss} > 100 GeV and m_{T} > 350 GeV.
Comparison between the expected and observed m_{T} and E_{T}^{miss} distributions in the different event categories. The expected distributions from the different background processes are stacked on top of each other. The shapes of inclusive process (SBI) of gg→ZZ→2l2ν and qq→ZZqq→2l2νqq for a r=10 scenario are superimposed. Dielectron (dimuon) events are shown on top (bottom). 0jet, at least 1 jet and VBF events are shown on the left, middle and right.
Summary of all systematic uncertainties on final event yields. The input uncertainty is quoted.
