“mT2:90” and “mT2:100” signal regions in the $ee$ (top), $\mathit{\mu }\mathit{\mu }$ (middle) and $e\mathit{\mu }$ (bottom) channels in ATLAS_CONF_2013_049. ${10}^4$ events of $pp\to {\tilde{\mathit{\chi }}}_1^{+}{\tilde{\mathit{\chi }}}_1^{-}$ process, followed by ${\tilde{\mathit{\chi }}}_1^{\pm }\to {\ell }_i^{\pm }\mathit{\nu }{\tilde{\mathit{\chi }}}_1^0$ via an on-shell ${\tilde{\ell }}_i$, are used. The masses are: $m_{{\tilde{\mathit{\chi }}}_1^{\pm }}=350$ GeV, $m_{\tilde{\ell }}=175$ GeV and $m_{{\tilde{\mathit{\chi }}}_1^0}=0$ GeV
