"Model-Independent Results Table, SR4$\ell$" of "Search for trilepton resonances from chargino and neutralino pair production in $\sqrt{s}$ = 13 TeV …
2021
Model-independent results where each row targets one $m_{Z\ell}$ bin of one SR and probes scenarios where a generic beyond-the-SM process is assumed to contribute only to that $m_{Z\ell}$ bin. The first two columns refer to the signal region and $m_{Z\ell}$ bin probed, while the third and fourth columns show the observed ($N{obs}$) and expected ($N{exp}$) event yields. The expected yields are obtained using a background-only fit of the CRs, and the errors include statistical and systematic uncertainties. The fifth and sixth columns show the observed 95% CL upper limit on the visible cross section ($\langle \epsilon \sigma \rangle^{95}_{obs}$) and on the number of signal events ($S^{95}_{obs…

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 expected 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 th…

2021
The observed data and pre-fit SM background expectation as a function of $L_{T}$ in SR4$\ell$. The first (last) bin includes underflow (overflow) events. The "Other" category mostly consists of $tWZ$, $ttW$, and $tZ$ processes. Only statistical uncertainties on the data and background expecation are shown.The bottom panel shows the ratio between the data and the background prediction

2021
$E^{miss,SF}_{T}$ kinematic distribution in the signal regions showing the data and the post-fit background in sr3$\ell$. The fit uses all CR and SRs, and the distributions are shown inclusively in $m_{Z\ell}$. The full event selection for each of the corresponding regions is applied except for the variable shown, where the selection is indicated by a blue arrow. the first (last) bin includes underflow (overflow) events. The other category mostly consists of $tWZ$, $t\bar{t}W$, and $tZ$ processes. The hatched bands indicate the combined theoretical, experimental, and MC statistical uncertainties. The bottom panel shows the ratio between the data and the post-fit background prediction.
"Expected co-NSLP limits" of "Search for displaced leptons in $\sqrt{s} = 13$ TeV $pp$ collisions with the ATLAS detector"
2021
Expected 95% CL exclusion sensitivity. The limit is displayed in the lifetime vs. $m(\tilde{\ell})$ plane where all slepton flavors and chiralities are mass degenerate.
"Observed co-NSLP limits" of "Search for displaced leptons in $\sqrt{s} = 13$ TeV $pp$ collisions with the ATLAS detector"
2021
Observed 95% CL exclusion sensitivity. The limit is displayed in the lifetime vs. $m(\tilde{\ell})$ plane where all slepton flavors and chiralities are mass degenerate.
"Observed LH selectron limits" of "Search for displaced leptons in $\sqrt{s} = 13$ TeV $pp$ collisions with the ATLAS detector"
2021
Observed 95% CL exclusion sensitivity. The limit is displayed in the lifetime vs. $m(\tilde{\ell})$ plane in SR-$ee$ targeting selectron production. Selectrons ($\tilde{e}_{R}$) refer to the scalar superpartners of right-handed electrons. Purple denotes the region excluded by LEP.
