Abstract

We have searched for chargino-neutralino production (χ^± ₁χ⁰ ₂) in 1.8 TeV pp collisions, followed by their leptonic decays χ^± ₁ → χ⁰ ₁ℓ^±ν and χ⁰ ₂→χ⁰ ₁ℓ⁺ℓ^-. These trilepton events are expected within a framework of the minimal supersymmetric standard model (MSSM). In a 19.1pb^-1 data sample collected with a Collider Detector at Fermilab, no trilepton events were observed. Upper limits on σ(pp → χ^± ₁χ⁰ ₂)BR(χ^± ₁→⁰ ₂→3ℓ + X) were obtained for various MSSM parameter space regions, yielding new 95% confidence level lower limits for the neutralino (χ⁰ ₂) mass which extend as high as 49GeV/c².

These trilepton events are expected within a framework of the minimal supersymmetric standard model (MSSM). In a 19.1pb-1 data sample collected with a Collider Detector at Fermilab, no trilepton events were observed. Upper limits on σ(pp → χ± 1χ0 2)BR(χ± 1→0 2→3ℓ + X) were obtained for various MSSM parameter space regions, yielding new 95% confidence level lower limits for the neutralino (χ0 2) mass which extend as high as 49GeV/c2.
