CP violation in supersymmetric theories:: t2→t1HH, t2→t1ZZ, t2→t1W+W-, t2→t1ZH

We study the decays t(2)-> t(1)HH, t(2)-> t(1)ZZ, t(2)-> t(1)W(+)W(-), and t(2)-> t(1)ZH, with an eye towards measuring the CP-violating supersymmetric parameters contained in these processes. We find that t(2)-> t(1)HH tends to have the largest CP asymmetry and width, and is perhaps the most favorable experimentally. These decays are sensitive primarily to phi(At), the phase of the trilinear coupling A(t).
