“Wa” (top), “Wb” (middle) and “Wc” (bottom) signal regions in ATLAS_CONF_2013_049. $5\times {10}^4$ events of $pp\to {\tilde{\mathit{\chi }}}_1^{+}{\tilde{\mathit{\chi }}}_1^{-}\to W^{+}{\tilde{\mathit{\chi }}}_1^0{W}^{-}{\tilde{\mathit{\chi }}}_1^0$ process are used. The masses are: $(m_{{\tilde{\mathit{\chi }}}_1^{\pm }},m_{{\tilde{\mathit{\chi }}}_1^0})=(100,0)$ GeV for Wa, $(m_{{\tilde{\mathit{\chi }}}_1^{\pm }},m_{{\tilde{\mathit{\chi }}}_1^0})=(140,20)$ GeV for Wb and $(m_{{\tilde{\mathit{\chi }}}_1^{\pm }},m_{{\tilde{\mathit{\chi }}}_1^0})=(200,0)$ GeV for Wc
