“mT2:90” and “mT2:100” signal regions in the $ee$ (top) and $\mathit{\mu }\mathit{\mu }$ (middle) channels in ATLAS_CONF_2013_049. $2\times {10}^3$ events of $pp\to {\tilde{e}}^{+}{\tilde{e}}^{-}\to e^{+}{\tilde{\mathit{\chi }}}_1^0{e}^{-}{\tilde{\mathit{\chi }}}_1^0$ and $pp\to {\tilde{\mathit{\mu }}}^{+}{\tilde{\mathit{\mu }}}^{-}\to {\mathit{\mu }}^{+}{\tilde{\mathit{\chi }}}_1^0{\mathit{\mu }}^{-}{\tilde{\mathit{\chi }}}_1^0$ processes are used for $ee$ and $\mathit{\mu }\mathit{\mu }$ channels, respectively. The masses are: $m_{\tilde{\ell }}=191$ GeV and $m_{{\tilde{\mathit{\chi }}}_1^0}=90$ GeV
