Abstract

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√⁰ ₂) 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: σ_σ ^± ₁χ⁰ ₂B(χ^± ₁χ⁰ ₂→3ℓ+X)<0.34pb, M_χ ^± ₁ χ81.5GeV/c², and M_χ ⁰ ₂ >82.2GeV/c² for tan >=2, μ=-600GeV/c², and M_q=M_g.
