The observed (solid black line) and expected (dashed black line) upper limits at 95% CL on $\sigma$(pp->X)B(X->HH->4b) for the narrow width spin-2 bulk graviton model. The green (yellow) bands represent one (two) standard deviations from the expected limit. The predicted theoretical cross sections are also shown.
