Multileptonic SUSY searches

A search for physics beyond the standard model using events with at least three leptons is presented. The data sample corresponds to 2.1~fb$^{-1}$ of integrated luminosity in pp collisions at $\sqrt{s}=7$~TeV collected by the CMS experiment at the LHC. Standard model backgrounds are suppressed by re...

description A search for physics beyond the standard model using events with at least three leptons is presented. The data sample corresponds to 2.1~fb$^{-1}$ of integrated luminosity in pp collisions at $\sqrt{s}=7$~TeV collected by the CMS experiment at the LHC. Standard model backgrounds are suppressed by requiring missing transverse energy, invariant mass of lepton pairs inconsistent with that of the ${Z}$ boson, or high jet activity. Control samples in data are used to ascertain the robustness of background evaluation techniques and to minimize the reliance on simulation. The observations are mostly consistent with expectations from standard model processes. These results are used to exclude previously unexplored regions of the supersymmetric parameter space assuming R-parity conservation with the lightest supersymmetric particle being either a neutralino or gravitino.
