Probing spontaneous CP-violation in supersymmetric models via B-decays

We study implications of spontaneous CP-violation in minimal susy models for CP-asymmetries in rare B,B̄-decays. In particular, we estimate characteristic values of the angles of the unitarity triangle and show that sizable CP-violating effects result from B−B̄ mixing only. Significant deviations from the SM predictions are pointed out.
