Search for chargino and neutralino production with three leptons and missing transverse momentum in the final states at $\sqrt{s}$ = 13 TeV with the ATLAS detector

Searches are presented for the direct production of a chargino and a neutralino, pp → $\chi^{±}_{1}$$\chi^{0}_{2}$, where the chargino decays to the lightest neutralino and the $W$ boson, $\chi^{±}_{1}$ → $\chi^{0}_{1}$($W^{±}$ → $\ell^{±}\nu$), while the neutralino decays to the lightest neutralino and either the $Z$ boson $\chi^{0}_{2}$ → $\chi^{0}_{1}$($Z$ → $\ell\ell$) or the 125 GeV Higgs boson, $\chi^{0}_{2}$ → $\chi^{0}_{1}$($h$ → $\ell\ell$). The final states considered for the search have large missing transverse momentum and three isolated light leptons (electrons and muons). e analysis is based on 36.1 fb$^{-1}$ of $\sqrt{s}$ = 13 TeV proton-proton collision data delivered by the Large Hadron Collider (LHC) and recorded with the ATLAS detector.
