noimg: Definition of the five signal regions based on the number of jets ($N_J$), the $\met$, $\meff$ requirements and the $b$-tagging operating point (OP).: Definition of the four control regions used to estimate the $\ttbar$+jets background.: Expected numbers of SM events and observed data events in the four \ttbar\ control regions. The contribution from $\ttbar$+jets events is taken directly from MC simulation. The column ``others'' includes the contributions from single top, $\ttbar$+$b\bar{b}$, $\ttbar$+$W$/$Z$ and $W$/$Z$+jets processes, also estimated from MC simulation, and the contribution from multi-jet events which is estimated with the jet smearing technique and accounts for less than 5\% of the total background. The column ``SM'' shows the total expected background and is the sum of the columns ``$\ttbar$+jets'' and ``others''. The uncertainties include all detector-related systematic uncertainties.

Distribution of \meff\ for SR4-L and SR4-T (top) and SR6-L and SR6-T (bottom). The hatched band shows the systematic uncertainty on the MC prediction, which includes both experimental uncertainties (among which JES and $b$-tagging uncertainties are dominant) and theoretical uncertainties on the background normalisation and shape. The label ``others'' includes the contributions from single top, $\ttbar$+$b\bar{b}$, $\ttbar$+$W$/$Z$, $W$/$Z$+jets and multi-jet processes. The lower plot in each figure shows the ratio of the observed distribution to that expected for the SM background. Two signal points (with small and large mass splitting between the gluino and the LSP) for the \emph{Gbb} and \emph{Gtt} models described in the text are overlaid.

Exclusion limits in the ($m^{}_{\gl},m^{}_{\bone}$) plane for the gluino-sbottom model (top left), in the ($m^{}_{\gl},m^{}_{\tone}$) plane for the gluino-stop model (top right) and in the ($m_{\tilde{g}},m_{\tilde{\chi}_1^0}$) plane for the \emph{Gbb} (bottom left) and \emph{Gtt} (bottom right) models. The dashed black and solid bold red lines show the 95\% CL expected and observed limits respectively, including all uncertainties except the theoretical signal cross-section uncertainty. The shaded (yellow) bands around the expected limits show the impact of the experimental uncertainties while the dotted red lines show the impact on the observed limit of the variation of the nominal signal cross-section by 1$\sigma$ theoretical uncertainty. Also shown for reference are the previous CDF~\protect\cite{gluinosbottomCDF,sbottomCDF}, D0~\protect\cite{sbottomD0} and ATLAS~\protect\cite{sbottom,PRD,dileptonSS,multijet} analyses.
