Examining the cancellation mechanism of a neutron EDM in a model with dilaton-dominated SUSY breaking

We examine the cancellation mechanism between the different contributions to the electric dipole moment of the neutron in a model with dilaton-dominated SUSY breaking. We find these accidental cancellations occur at few points in parameter space. For a wide region of this space we must constrain the phase of mu to be of order 10(-1) and have the phases of A and mu strongly correlated in order to have a small neutron EDM. Moreover, we consider the indirect CP violation parameter epsilon in this region where the electric dipole moment is less than the experimental limit and find that we can generate epsilon of order 10(-6).
