"Aux : Figure 4b" 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"

$E^{T}_\text{miss}$ for events with at least 3 jets, one $b$-tagged jets 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. In order to enhance the contribution from fake or non-prompt leptons from $t\bar{t}$ events, the events are required to have at least one different flavour lepton pair and no same flavour pair with opposite charge.
