We perform a detailed study of the decays of the heavier top and bottom squarks (t̃2 and b̃2) in the Minimal Supersymmetric Standard Model (MSSM). We show that the decays into Higgs or gauge bosons, i.e. t̃2 → t̃1 + (h0, H0, A0 or Z0), t̃2 → b̃1,2 + (H+ or W+), and the analogous b̃2 decays, can be dominant in a wide range of the model parameters due to the large Yukawa couplings and mixings of t̃ and b̃. Compared to the conventional decays into fermions, such as t̃2 → t + ( χ̃0i or g̃) and t̃2 → b + χ̃+j, these bosonic decay modes can have significantly different decay structures and distributions. This could have an important impact on the search for t̃2 and b̃2 and the determination of the MSSM parameters at future colliders.
