The direct production of chargino-neutralino, pp→χ̃±1χ̃02, followed by their decays via intermediate WH states (χ̃±1χ̃02→W±Hχ̃01χ̃01), where H is the 125-GeV Standard Model Higgs boson, is a very important channel for the search for electroweak supersymmetry at the Large Hadron Collider. Amongst others, the search can be performed in the channel where both the W and the H decay fully leptonically (χ̃±1→χ̃01(W±→ℓ±ν) and χ̃02→χ̃01(H→ℓℓ)), yielding three leptons in final state. Results are presented from this search using 36.1 fb−1 of √s=13 TeV proton-proton collision data recorded with the ATLAS detector, together with an outlook for the full Run-2 analysis.
