Abstract
We have searched for evidence of supersymmetry with the Collider Detector at Fermilab using trilepton events in p$\bar{p}$ collisions at √s = 1.8 TeV. In the Minimal Supersymmetric Standard Model (MSSM), we expect trilepton events from chargino-neutralino ($\tilde{χ}$±1$\tilde{χ}$02) pair production, with subsequent decay into leptons. In all possible combinations of electron and muon channels, we observe no candidate events in 107 pb-1 of data. We present limits on chargino and neutralino production within the framework of a supergravity inspired MSSM: σ$\tilde{χ}$±1$\tilde{χ}$02 ∙ BR($\tilde{χ}$±1$\tilde{χ}$02 → 3l + X) < 0.34 pb and M$\tilde{χ}$±1} > 81.5 GeV/c2 for tan β = 2, μ = -600 GeV/c2$\tilde{q}$ = M$\tilde{g}$. We also present limits on a SU(5) x U(1) supergravity model and a 4 and 1/2 parameter Minimal SUGRA model.
