- Kurzfassung
- Results of a search for supersymmetric particles in final states with four or more leptons (electrons or muons) and missing transverse momentum with the ATLAS detector are presented. The analysis uses a sample corresponding to 2.06 fb−1 integrated luminosity of proton-proton data recorded in 2011 at a centre-of-mass energy of 7 TeV. With an inclusive selection we observe 4 events, while 1.7±0.9 are expected from Standard Model processes. Applying a Z-veto for leptons pairs with same flavour and opposite charge, we observe no events for 0.7±0.8 events expected. Within the selection acceptance, we determine effective 95% C.L. cross section upper limits for new phenomena of 3.45 fb and 1.46 fb for the inclusive and exclusive selections, respectively
