Abstract
A search for the direct production of charginos and neutralinos in final states with three leptons and missing transverse momentum is presented. 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. 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 (Formula presented) and next-to-lightest neutralino (Formula presented) production with decays to lightest neutralino (Formula presented) via either all three generations of sleptons, staus only, gauge bosons, or Higgs bosons, (Formula presented) and (Formula presented) masses are excluded up to 700 GeV, 380 GeV, 345 GeV, or 148 GeV respectively, for a massless (Formula presented).
