The results of a search for electroweakino pair production pp ightarrow ilde{chi }^pm _1 ilde{chi }^0_2pp→ χ ~ 1 ± χ ~ 2 0 in which the chargino ( ilde{chi }^pm _1 χ ~ 1 ± ) decays into a W boson and the lightest neutralino ( ilde{chi }^0_1 χ ~ 1 0 ), while the heavier neutralino ( ilde{chi }^0_2 χ ~ 2 0 ) decays into the Standard Model 125 GeV Higgs boson and a second ilde{chi }^0_1 χ ~1 0 are presented. The signal selection requires a pair of b-tagged jets consistent with those from a Higgs boson decay, and either an electron or a muon from the W boson decay, together with missing transverse momentum from the corresponding neutrino and the stable neutralinos. The analysis is based on data corresponding to 139 mathrm {fb}^{-1}fb −1 of sqrt{s}=13 s=13 TeV pp collisions provided by the Large Hadron Collider and recorded by the ATLAS detector.
