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 vs = 8TeV 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 (���X��1) and next-to-lightest neutralino (X���0 2) production with decays to lightest neutralino (���X0 1) via either all three generations of sleptons, staus only, gauge bosons, or Higgs bosons, ���X�� 1 and ���X0 2 masses are excluded up to 700GeV, 380GeV, 345GeV, or 148GeV respectively, for a massless ���X0 1.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
