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 10%-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.

针对具有10%宽度的自旋2体引力子（spin-2 bulk graviton）模型，给出了σ(pp→X)B(X→HH→4b)的95%置信度（CL）上限的观测结果（黑色实线）与预期结果（黑色虚线）。绿色（黄色）带分别代表相对于预期上限的一（二）倍标准偏差范围。同时展示了该过程的理论预言产生截面。
