We have searched in pp collisions at √s=1.8TeV for events with three charged leptons and missing transverse energy. In the minimal supersymmetric standard model, we expect trilepton events from chargino-neutralino (√±1√02) pair production, with subsequent decay into leptons. We observe no candidate e+e-e±, e+e-μ±, e±μ+μ-, or μ+μ-μ± events in 106pb-1 integrated luminosity. We present limits on the sum of the branching ratios times cross section for the four channels: σσ±1χ02B(χ±1χ02→3ℓ+X)<0.34pb, Mχ±1 χ81.5GeV/c2, and Mχ02 >82.2GeV/c2 for tan >=2, μ=-600GeV/c2, and Mq=Mg. © 1998 The American Physical Society.
