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 $\tilde\chi^{\pm}{1}/\tilde\chi^{0}{1}$ mass and branching fraction to $Z$ bosons. grey numbers represent the observed upper cross-section limits. curves are derived separately when requiring that the charged-lepton decays of the $\tilde\chi^{\pm}{1}/\tilde\chi^{0}{1}$ are to an electron only. 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. the sum of the $\tilde\chi^{\pm}{1}/\tilde\chi^{0}{1}$ branching fractions to $W$, $Z$, and Higgs bosons is unity for each point, and the branching fractions to $W$ and Higgs bosons are chosen so as to be equal everywhere.
