"Observed and expected limits (model D)" of "Search for Resonant Production of Dark Quarks in the Dijet Final State with the ATLAS Detector"

Observed and expected limits at 95% CL on the cross-section times branching ratio for the production of dark quarks through a $Z^\prime$ as a function of the $Z^\prime$ mass for model D (see the text for details). The darker and lighter shaded bands around the expected limits represent the $\pm 1 \sigma$ and $\pm 2 \sigma$ uncertainty range, respectively.针对模型D，给出了以Z'质量为自变量时，通过Z'产生暗夸克过程的截面与分支比乘积的95%置信度观测极限与预期极限（详细说明见正文）。预期极限周围的深色与浅色阴影带分别对应±1σ和±2σ的不确定度范围。
