Resumen:
We study the decays stop2->stop1 H H, stop2->stop1 Z Z, stop2->stop1 W+ W- and stop2->stop1 Z H, with an eye towards measuring the CP-violating supersymmetric parameters contained in these processes. We find that stop2->stop1 H H tends to have the largest CP asymmetry and width, and is perhaps the most favourable experimentally. These decays are sensitive primarily to phi_At, the phase of the trilinear coupling A_t.
