T-odd correlations in the decay of scalar fermions.

We define a CP-sensitive asymmetry in the sfermion decays F → F X_j⁰ q q, based on triple product correlations between the momenta of the outgoing fermions. We study this asymmetry in the MSSM with complex parameters. We show that the asymmetry is sensitive to the phases of the parameters µ and M₁. The leading contribution stems from the decay chain f → f X_j⁰ → fX_j⁰ Z → f X_j⁰ l l (f X_j⁰ q q), which we obtain analytic formulae for the amplitude squared. The asymmetry can go up to 3% for f → f X₁⁰ l l, and up to 20% for f → f X_j⁰ q q. We also estimate the rates necessary to measure the asymmetry. [ABSTRACT FROM AUTHOR]
