Fraction of RS graviton events selected by the two analysis categories for 500 GeV $ < {m_ {\mathrm{G} } } < $ 4500 GeV and $\tilde{ \kappa } =$ 0.01, 0.1, 0.2.



png ; pdf ; Figure 2-a:

Comparison between the predicted and observed invariant mass distribution of electron pairs obtained after the application of energy scale and resolution corrections. Distributions are shown for events where both electrons are reconstructed in the barrel (a) and events where one electron is in the endcaps (b). The simulation predictions are scaled to match the number of events observed in data.

Upper limit on the production of a narrow RS graviton obtained with the combined analysis. For $ {m_ {\mathrm{G} } } < $ 850 GeV, the results obtained at $ \sqrt {s} =$ 8 TeV with the analysis described in Ref.[10] are combined with those obtained at $\sqrt {s} =$ 13 TeV. For $ {m_ {\mathrm{G} } } >$ 850 GeV the results of the analysis described in Ref.[11] obtained at 8 TeV are combined with those obtained at $ \sqrt {s} =$ 13 TeV.
