    AnnotationA search is presented for the direct pair production of a chargino and a neutralino pp→χ~±1χ~02 , where the chargino decays to the lightest neutralino and the W boson, χ~±1→χ~01(W±→ℓ±ν) , while the neutralino decays to the lightest neutralino and the 125 GeV Higgs boson, χ~02→χ~01(h→bb/γγ/ℓ±νqq) . The final states considered for the search have large missing transverse momentum, an isolated electron or muon, and one of the following: either two jets identified as originating from bottom quarks, or two photons, or a second electron or muon with the same electric charge. The analysis is based on 20.3 fb−1 of s√=8 TeV proton–proton collision data delivered by the Large Hadron Collider and recorded with the ATLAS detector.
