Trilepton + low Et electrons

Search for Chargino-Neutralino Production in mSUGRA Model in a Di-electron + track Channel

We report in this page the analysis result of searching for Chargino-Neutralino production in mSUGRA Model in a di-electron + track channel at CDF Run2. The search assumes R-parity conservation. A key feature of this analysis is that the lepton p_T reach is as low as 4 GeV which results in higher acceptance. We expect 0.36 ± 0.24 background events in 224 pb^-1 of data and we observe 2 events.
