Search for direct production of charginos and neutralinos in events with three leptons and missing transverse momentum in sqrt(s) = 8TeV pp collisions with the ATLAS detector

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 sqrt(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 (${\tilde{\chi }}_1^{\pm }$) and next-to-lightest neutralino (${\tilde{\chi }}_2^0$) production with decays to lightest neutralino (${\tilde{\chi }}_1^0$) via either all three generations of sleptons, staus only, gauge bosons, or Higgs bosons, ${\tilde{\chi }}_1^{\pm }$ and ${\tilde{\chi }}_2^0$ masses are excluded up to 700 GeV, 380 GeV, 345 GeV, or 148 GeV respectively, for a massless ${\tilde{\chi }}_1^0$.
