Resumen:
Supersymmetric (SUSY) theories include many new parameters, some of which are CP-violating. Assuming that SUSY is found at a future high-energy collider, we examine the decay t?2→t?1τ−τ+ with an eye to obtaining information about the new CP phases. We show that there are two CP-violating asymmetries which can be large in some regions of the SUSY parameter space. These involve measuring one or both of the τ spins. These asymmetries are particularly sensitive to ϕAt, the phase of the trilinear coupling At.
