| \textit{Left:} The reconstructed mass, $m_{\beta\gamma}$, derived from the $dE/dx$ measurements in the pixel tracker against the mass reconstructed from the time-of-flight measurement, $m_{\beta}$, for data, signal and expected background events~\cite{bib:ATLAS:Paper:Pixel+ToF_13TeV}. The black dotted line indicates the signal region used for this specific signal model. \textit{Right:}~The observed (red line) and expected (black dashed line) 95\% cross section upper limit for stable gluinos~\cite{bib:ATLAS:Paper:Pixel+ToF_13TeV}. The blue band indicates the theoretical cross section. The green and yellow bands correspond to the 1 and 2\,$\sigma$ uncertainty of the expected upper limit, respectively. |
