“noZc” signal region in ATLAS_CONF_2013_035. $5\times {10}^3$ events of $pp\to {\tilde{\mathit{\chi }}}_1^{\pm }{\tilde{\mathit{\chi }}}_2^0$ process, followed by ${\tilde{\mathit{\chi }}}_1^{\pm }\to {\ell }^{\pm }\mathit{\nu }{\tilde{\mathit{\chi }}}_1^0$ and ${\tilde{\mathit{\chi }}}_2^0\to {\ell }^{+}{\ell }^{-}{\tilde{\mathit{\chi }}}_1^0$ both via an on-shell ${\tilde{\ell }}_L$, are used. The masses are: $m_{{\tilde{\mathit{\chi }}}_1^{\pm }}=m_{{\tilde{\mathit{\chi }}}_2^0}=500$ GeV, $m_{{\tilde{\ell }}_L}=250$, $m_{{\tilde{\mathit{\chi }}}_1^0}=0$ GeV
