Abstract

We study the decays of top squarks (~t_1,2) and bottom squarks (~b_1,2) in the Minimal Supersymmetric Standard Model (MSSM) with complex parameters A_t, A_b, mu and M₁. We show that including the corresponding phases strongly affects the branching ratios of ~t_1,2 and ~b_1,2 decays in a large domain of the MSSM parameter space. This could have an important impact on the search for ~t_1,2 and ~b_1,2 and the determination of the underlying MSSM parameters at future colliders.
