Abstract

We report the first fully general numerical calculation of the neutron and electron dipole moments, including the seven significant phases. We find that there are major regions in the parameter space where none of the phases are required to be small, contrary to the conventional wisdom. The electric dipole moments do provide useful constraints, allowing other regions of parameter space to be carved away. We keep all superpartner masses light, and so agreement with experimental limits arises purely from interesting relations among soft breaking parameters.
