Jet multiplicity distributions in VR$^{1\ell 4b}_A$ for an integrated luminosity of 36.1 fb$^{-1}$. The contributions from all SM backgrounds are shown as a histogram stack; the bands represent the total uncertainty. The "Others" category contains the contributions from $t\bar{t} h$, $t\bar{t} WW$, $t\bar{t} t$, $t\bar{t} t\bar{t}$, $Wh$, and $Zh$ production.针对积分亮度为36.1 fb⁻¹的VR$^{1ell 4b}_A$分析区域，给出其喷注多重数分布。所有标准模型（Standard Model, SM）本底的贡献以堆叠直方图形式呈现；误差带代表总不确定度。"其他"类别涵盖$tar{t}h$、$tar{t}WW$、$tar{t}t$、$tar{t}tar{t}$、$Wh$以及$Zh$产生过程的贡献。
