Analysis of CP Violation in Neutralino Decays to Tau Sleptons

الأصل · EN

In the minimal supersymmetric standard model, tau sleptons τ₁,₂ and neutralinos χ⁰₁,₂ are expected to be among the lightest supersymmetric particles that can be produced copiously at future e+e- linear colliders. We analyze τ pair and χ₁⁰ χ₂⁰ production under the assumption m χ₁⁰ < m τ₁ < m χ₂⁰, allowing the relevant parameters of the SUSY Lagrangian to have complex phases. We show that the transverse and normal components of the polarization vector of the τ lepton produced in χ₂⁰ decays offer sensitive probes of these phases.
