"1l4b Exp limit MSTOP2 = 650 GeV MN01 = 200 GeV" of "Search for direct top squark pair production in events with a Higgs or $Z$ boson, and missing transverse momentum in $\sqrt{s}=13$ TeV $pp$ collisions with the ATLAS detector"

Expected exclusion limits at 95% CL from the analysis of $36.1 \; \text{fb}^{-1}$ of 13 TeV $pp$ collision data as a function of the $\tilde{t}_2$ branching ratio for $\tilde{t}_2 \to \tilde{t}_1 Z$, $\tilde{t}_2 \to \tilde{t}_1 h$ and $\tilde{t}_1 \to t\tilde{\chi}^0_1$ for the $1\ell 4b$ selection for the model $m(\tilde{t}_2)=650$ GeV $m(\tilde{\chi}^0_1)=200$ GeV.

本分析基于积分亮度为36.1 fb⁻¹的13 TeV质子-质子（$pp$）碰撞数据，针对模型参数$m( ilde{t}_2)=650$ GeV、$m( ilde{chi}^0_1)=200$ GeV的情景，采用1轻子4b喷注（$1ell 4b$）事例选择方案，给出了第二轻顶超对称夸克（$ ilde{t}_2$）在$ ilde{t}_2 o ilde{t}_1 Z$（第二轻顶超对称夸克衰变至第一轻顶超对称夸克与Z玻色子）、$ ilde{t}_2 o ilde{t}_1 h$（第二轻顶超对称夸克衰变至第一轻顶超对称夸克与希格斯玻色子）以及$ ilde{t}_1 o t ilde{chi}^0_1$（第一轻顶超对称夸克衰变至顶夸克与最轻中性伴子）衰变模式下的分支比与95%置信度预期排除极限的函数关系。
