Small Flavor Conserving CP Violation in Superstring Models

Abstract
It is well known that supersymmetric models allow new sources for CP violation that arise from soft supersymmetry breaking terms. If unsuppressed, these new CP-violating phases would give too large a neutron electric dipole moment. We discuss a mechanism for suppressing SUSY phases in string-inspired supergravity models in which supersymmetry is assumed to be broken by the auxiliary components of the dilaton and moduli superfields.
