"Triangle, 500 GeV, $\ell=\tau$, Exp_0" of "Search for trilepton resonances from chargino and neutralino pair production in $\sqrt{s}$ = 13 TeV $pp$ collisions with the ATLAS detector"

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 $\tau$-leptons for a mass of 500 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.
