Distribution of the four-lepton reconstructed mass in full analysis mass range for the sum of the 4e, 4μ, and 2e2μ channels. Points represent the data, shaded histograms represent the background and dotted-shaded histogram the gg+VV→ZZ expectations. The expected distributions are presented as stacked histograms. The measurements are presented for of the data collected at √s = 8 TeV. [100-800] GeV range and with variable bin width. |

Distribution of the four-lepton reconstructed mass in full analysis mass range with a requirement on the MELA discriminant Dgg < 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 dotted-shaded histogram the gg+VV→ZZ expectations. The expected distributions are presented as stacked histograms.

Distribution of the expected four-lepton 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 four-lepton cross-section 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 off-shell region by this scaling factor is expected. |
