The analysis is based on 20.3 fb-1 of sv = 8 TeV proton-proton collision data delivered by the Large Hadron Collider and recorded with the ATLAS detector. Observations are consistent with the Standard Model expectations and limits are set in R-parity-conserving phenomenological Minimal Supersymmetric Standard Models and in simplified supersymmetric models, significantly extending previous results. For simplified supersymmetric models of direct chargino (?~1±) and next-to-lightest neutralino (?~20) production with decays to lightest neutralino (?~10) via either all three generations of sleptons, staus only, gauge bosons, or Higgs bosons, (?~1±) and (?~20) masses are excluded up to 700 GeV, 380 GeV, 345 GeV, or 148 GeV respectively, for a massless (?~10).
