"Efficiency SRA 7" of "Search for direct top squark pair production in final states with two leptons in $\sqrt{s} = 13$ TeV $pp$ collisions with the ATLAS detector"

SRA$^{2-body}_{180}$ Different Flavour efficiency for each signal model, assuming $\tilde{t}_1$ pair production, decaying via $\tilde{t}_1 \rightarrow b \tilde{\chi}^{\pm}_1$ with 100% branching ratio.$SRA^{2-body}_{180}$：各信号模型对应不同的味效率，本数据集假设标量顶夸克（$ ilde{t}_1$）成对产生，且以100%的分支比（branching ratio）通过衰变道 $ ilde{t}_1 ightarrow b ilde{chi}^{pm}_1$ 发生衰变。
