Resumen:
A search for the direct production of charginos and neutralinos in final
states with three electrons or muons and missing transverse momentum is
presented. The analysis is based on 4.7 fb-1 of sqrt(s) = 7 TeV
proton-proton collision data delivered by the Large Hadron Collider and
recorded with the ATLAS detector. Observations are consistent with
Standard Model expectations in three signal regions that are either
depleted or enriched in Z-boson decays. Upper limits at 95% confidence
level are set in R-parity conserving phenomenological minimal
supersymmetric models and in simplified models, significantly extending
previous results.
