Abstract (data abstract)
CERN-LHC. Data are presented from the measurements of final states comprising three leptons (electrons or muons) and missing transverse energy in proton proton collisions at a centre-of-mass energy of 7 Tev. The data sample has a total integrated luminosity of 4.7fb-1 and is interpreted in the pMSSM and in simplified models using different signal regions.
