Search for trilepton SUSY signal at CDF

The production of chargino-neutralino and their subsequent leptonic decay is one of the most promising supersymmetry (SUSY) signatures at the Tevatron collider. We present a complete CDF search for trileptons and missing transverse energy associated with this process. To increase our sensitivity to SUSY signals (or any other new phenomena) we include low-pt electrons and muons (pT$>$5 GeV/c), low dilepton mases (Mll$>$10 GeV/c$^2$), forward leptons ($|\eta|>$1), loose leptons (isolated tracks that do not pass ordinary lepton selection) and tau-jets from hadronic tau decays. Special care is taken for the light-flavor and heavy-flavor QCD background that is significant in some of the kinematic regions we explore.
