Resolution to the supersymmetric CP problem with large soft phases via D-branes

We examine the soft supersymmetry breaking parameters that result from various ways of embedding the standard model (SM) on D-branes within the type I string picture, allowing the parameters to have large CP-violating phases. One embedding naturally provides the relations among soft parameters to satisfy the electron and neutron electric dipole moment constraints even with large phases, while with other embeddings large phases an not allowed. The results generally suggest how low energy data might teach us about Planck scale physics.
