Abstract

We study the decays of top squarks and bottom squarks in the Minimal Supersymmetric Standard Model with complex parameters A_t, A_b and mu. In a large region of the supersymmetric parameter space the branching ratios of stop₁ and sbottom₁ show a pronounced phase dependence. This could have an important impact on the search for stop₁ and sbottom₁ at a future linear collider and on the determination of the supersymmetric parameters.
