Impact of CP phases on the search for top and bottom squarks
Abstract
We study the decays of top squarks (~t1,2) and bottom squarks (~b1,2) in the Minimal Supersymmetric Standard Model (MSSM) with complex parameters At, Ab, mu and M1. We show that including the corresponding phases strongly affects the branching ratios of ~t1,2 and ~b1,2 decays in a large domain of the MSSM parameter space. This could have an important impact on the search for ~t1,2 and ~b1,2 and the determination of the underlying MSSM parameters at future colliders.
