Exclusion curves for the simplified model of $\tilde\chi^{\pm}_{1}\tilde\chi^{\mp}_{1} + \tilde\chi^{0}_{1}\tilde\chi^{0}_{1}$ pair-production as a function of $\tilde\chi^{\pm}_{1}/\tilde\chi^{0}_{1}$ branching fraction to $Z$ and Higgs bosons. Results are shown for the charged-lepton decays of $\tilde\chi^{\pm}_{1}/\tilde\chi^{0}_{1}$ into electrons for a mass of 600 GeV. Grey numbers represent the expected upper cross-section limits. The expected 95/% CL exclusion (dashed black line) is shown with $\pm1~\sigma_{\mathrm{exp}}$ (yellow band) from systematic and statistical uncertainties on the expected yields. The observed 95/% CL exclusion (solid red line) is shown with the $\pm1~\sigma_{\mathrm{theory}}^{\mathrm{SUSY}}$ (dotted red line) from signal cross section uncertainties on the signal models. The phase-space excluded by the search is shown in the shaded color.
