Triple product correlations in top squark decays

We propose several T-odd asymmetries in the decay chains of the top squarks tm→tχk0 and t→bW+→blν and χk0→l±ln±→l±l±χ10, for l=e,μ,τ. We calculate the asymmetries within the Minimal Supersymmetric Standard Model with complex parameters M1, μ, and At. We give the analytic formulae for the decay distributions. We present numerical results for the asymmetries and estimate the event rates necessary to observe them. The largest T-odd asymmetry can be as large as 40%
