Observed event yields (points with error bars) and background expectations (filled solid histograms) as a function of the diphoton invariant mass. Photons are required to be isolated, with $\ET>70$\GeV and $|\eta|<1.44$. The shaded band around the background estimation corresponds to the average systematic uncertainty over the spectrum. The precise per-bin uncertainty is not provided for the sake of clarity. The last bin includes the sum of all contributions for $M_{\gamma\gamma}>2.0\TeV$. The simulated distributions for two, non-excluded signal hypotheses are shown for comparison as dotted (ADD) and dashed (RS) lines.

Signal cross section $S$ parameterization as a function of the strength of the ED effects, $\eta_G$ (\CMSleft) and as a function of $1/\MS^4$ for the HLZ $\ned=2$ case (\CMSright).

The 95\% CL exclusion region for the RS1 graviton model in the $M_1$--$\tilde{k}$ plane. The expected limits coincide very closely with the measured limits and so are not shown in the figure. Also shown are bounds due to electroweak constraints and naturalness ($\Lambda_{\pi}>10\TeV$). Perturbativity requirements bound $\tilde{k}\lesssim0.10$.
