"Aux : Figure 1a" 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"

Illustration of the best expected signal region per signal grid point for the $\tilde{t}_2 \rightarrow h\tilde{t}_1$ models with $\tilde{t}_1\to t\tilde{\chi}^0_1$. This mapping is used for the final combined exclusion limits 1 = A, 2 = B, 3 = C.针对满足$ ilde{t}_1 o t ilde{chi}^0_1$衰变模式的$ ilde{t}_2 ightarrow h ilde{t}_1$模型，各信号网格点对应的最优预期信号区域示意图。该映射关系用于最终联合排除限的设定，其中1对应A、2对应B、3对应C。
