The analysis uses a dataset of $pp$ collisions corresponding to an integrated luminosity of 36.1 fb$^{-1}$, recorded with the ATLAS detector at the Large Hadron Collider at a centre-of-mass energy of 13 TeV. No significant deviation from the Standard Model background expectation is observed. Limits are derived in scenarios of $\\tilde{\\chi}_{1}^{+}\\tilde{\\chi}_{1}^{-}$ pair production and of $\\tilde{\\chi}_{1}^{\\pm}\\tilde{\\chi}_{2}^{0}$ and $\\tilde{\\chi}_{1}^{+}\\tilde{\\chi}_{1}^{-}$ production in simplified models where the neutralinos and charginos decay solely via intermediate left-handed staus and tau sneutrinos, and the mass of the $\\tilde{\\tau}_{\\mathrm L}$ state is set to be halfway between the masses of the $\\tilde{\\chi}_{1}^{\\pm}$ and the $\\tilde{\\chi}_{1}^{0}$. Chargino masses up to 630 GeV are excluded at 95% confidence level in the scenario of direct production of $\\tilde{\\chi}_{1}^{+}\\tilde{\\chi}_{1}^{-}$ for a massless $\\tilde{\\chi}_{1}^{0}$. Common $\\tilde{\\chi}_{1}^{\\pm}$, $\\tilde{\\chi}_{2}^{0}$ masses up to 760 GeV are excluded in the case of production of $\\tilde{\\chi}_{1}^{\\pm}\\tilde{\\chi}_{2}^{0}$ and $\\tilde{\\chi}_{1}^{+}\\tilde{\\chi}_{1}^{-}$ assuming a massless $\\tilde{\\chi}_{1}^{0}$. Exclusion limits for additional benchmark scenarios with large and small mass-splitting between the $\\tilde{\\chi}_{1}^{\\pm}$ and the $\\tilde{\\chi}_{1}^{0}$ are also studied by varying the $\\tilde{\\tau}_{\\mathrm L}$ mass between the masses of the $\\tilde{\\chi}_{1}^{\\pm}$ and the $\\tilde{\\chi}_{1}^{0}$.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.78377.v1/t1","@type":"Dataset","description":"The $E_{\\mathrm T}^{\\mathrm{miss}}$ distribution in the $W$-CR region.
