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.

N2 - 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: σσ ± 1χ0 2B(χ± 1χ0 2→3ℓ+X)<0.34pb, Mχ ± 1 χ81.5GeV/c2, and Mχ 0 2 >82.2GeV/c2 for tan >=2, μ=-600GeV/c2, and Mq=Mg.
