- Kurzfassung
- This note describes an interpretation of a search for supersymmetry in final states with at least four isolated leptons (electrons or muons) and missing transverse momentum. The search used 2.06 fb−1 of proton-proton collision data collected with the ATLAS experiment, and found no significant excess above expectations from Standard Model processes. Limits are shown for the Minimal Supergravity/Constrained Minimal Supersymmetric Standard Model (mSUGRA/CMSSM) with m0=A0=0, mu>0 and one R-parity violating parameter lambda_121=0.032 at the grand unification scale m_GUT. Keeping these parameters fixed, values of m_1/2<800 GeV are excluded at 95% CL if tan(beta)<40 and m_stau_1>80 GeV. These are the first limits from the LHC experiments on a model with a stau_1 as the lightest supersymmetric particle.
