Search for supersymmetry in opposite sign dilepton final states with the CMS experiment

A search for physics beyond the standard model in final states with opposite-sign isolated lepton pairs accompanied by hadronic jets and missing transverse energy is presented. This signature is a typical signature in many supersymmetric models. In a study based on simulation the discovery potential and possible parameter extraction of a specific supersymmetric model is evaluated. The search is then performed using hadron-hadron data from the LHC recorded with the CMS detector during 2010, corresponding to an integrated luminosity of 36~pb^{-1}. No evidence for an anomalous event yield beyond Standard Model expectations is found. An upper limit on the non Standard Model contribution in the signal region is deduced from the experimental results. This limit is interpreted in the constrained minimal supersymmetric model. Additional information is provided to allow testing the exclusion of other specific models of physics beyond the SM.
