Search for supersymmetry at CDF
We have conducted a search for trilepton events from supersymmetry (SUSY) in p{bar p} collisions at {radical}s = 1.8 TeV. In the Supersymmetric Standard Model (MSSM), trilepton events are expected from chargino-neutralino ({tilde {chi}}{sub 1}{sup {plus_minus}}{tilde {chi}}{sub 2}{sup {minus}0}) pair production, with subsequent decay into leptons. In all possible combinations of electron and muon channels in 19 pb{sup {minus}1} data, we observe no events which pass our trilepton selection criteria. Employing the GUT hypothesis within the framework of the MSSM, our preliminary excludes M({tilde {chi}}{sub 1}{sup {plus_minus}}) <46 GeV/c{sup 2} c{sup 2} for {minus}500 < {mu} < {minus}400 GeV, 2.0 < tan({beta}) < 15.0, and M({tilde q}) = 1.2 {times} M({tilde g}).
