Abstract

We have analyzed the supersymmetric tri-lepton signals for sparticle searches at the Tevatron in the minimal supersymmetric standard model with general CP phases without generational mixing. The CP phases may affect strongly the chargino and neutralino mass spectra and σ(pp̄ → X₁/^-X₂/⁰) as well as B(X₁^- → X ₁/⁰ l^- ν) and B(X₂/⁰ → X₁/⁰ l⁺ l^-). Even under the stringent constraints from the electron electric dipole moment the CP phases can lead to a minimum of the tri-lepton event rate for their non-trivial values.
