title: "excl_WH_exp_down" of "Search for direct production of electroweakinos in final states with one lepton, jets and missing transverse momentum in pp collisions at $\sqrt{s}=13$ TeV with the ATLAS detector"

description: Model-dependent exclusion contour at 95 CL on the chargino and a next-to-lightest neutralino mass versus the mass difference between chargino and LSP in the C1N2-Wh model. The observed limit is given by the solid line with the signal cross-section uncertainties shown by the dotted lines as indicated in the text. Expected limits are given by the dashed line with uncertainties shown by the shaded band. The observed and expected limit contours from the previous ATLAS analysis of the same data sample using standard cut-and-count methods are also shown for comparison.
description: The results of three searches for electroweakino pair production $pp \rightarrow \tilde\chi^\pm_1 \tilde\chi^0_2 / \tilde{\chi}_1^{+}\tilde{\chi}_1^{-}$ in which the chargino ($\tilde\chi^\pm_1$) decays into a $W$ boson and the lightest neutralino ($\tilde\chi^0_1$), while the heavier neutralino ($\tilde\chi^0_2$) decays into either a $Z$ or a Higgs boson and a second $\tilde\chi^0_1$ are presented. The searches are performed in events with one isolated lepton, jets and missing transverse momentum, using \(pp\) collisions provided by the LHC at a centre-of-mass energy of 13TeV. Data collected with the ATLAS detector between 2015 and 2018 are used, corresponding to an integrated luminosity of $139~\mathrm{fb}^{-1}$. No significant deviation from the expected Standard Model background is observed, and limits are set on the direct production of the electroweakinos in simplified models. Searches exploiting large radius jets to identify hadronically decaying $W$ and $Z$ bosons complement the previous ATLAS limits. In the $\tilde{\chi}_1^{+}\tilde{\chi}_1^{-}$ model, masses of $\tilde{\chi}^{\pm}_{1}$ ranging from 260 to 520GeV are excluded at 95% confidence level for a massless $\tilde{\chi}^{0}_{1}$. In the $\tilde\chi^\pm_1 \tilde\chi^0_2 $ model with $\tilde\chi^0_2$ decaying via a $Z$ boson, masses of $\tilde{\chi}^{\pm}_{1}/\tilde{\chi}^{0}_{2}$ ranging from 260 to 420GeV are excluded at 95% CL for a massless $\tilde{\chi}^{0}_{1}$. Utilizing a BDT discriminant, the search targeting $\tilde\chi^\pm_1 \tilde\chi^0_2 $ models with $\tilde\chi^0_2$ decaying via a Higgs boson and mass-splitting between the mass-degenerate $\tilde\chi^\pm_1$ and $\tilde\chi^0_2 $ as small as the Higgs boson mass and the LSP exceed previous constraints by up to 40GeV in the range of 200-260GeV and 280-470GeV in $m (\tilde{\chi}_1^{+}/\tilde{\chi}^{0}_{2})$.
