"Figure 20 [bbll/bbWW]" of "Combination of ATLAS and CMS searches for Higgs boson pair production at $\sqrt{s} = 13$ TeV"

Observed and expected negative log-likelihood ($-2\ ln\ \Lambda$) values as a function of $\kappa_{2V}$ for the input ATLAS bbll and CMS bbWW analyses . All the other Higgs boson couplings are fixed to their SM predictions.

观测与预期的负对数似然（$-2lnLambda$）数值随$kappa_{2V}$的变化关系，对应输入的ATLAS bbll与CMS bbWW实验分析。其余所有希格斯玻色子耦合常数均固定为标准模型（Standard Model, SM）的理论预言值。
