Abstract

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 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.

Item Type: Article
Additional Information: I established and have led for five years (2007-12) the ATLAS SUSY Multilepton physics group, which searches for supersymmetry signals in final states with three or more leptons at ATLAS. I successfully led this group to first publications using the ATLAS 2011 dataset. I was lead author of the analysis presented in this paper and one of the three editors of the paper.
