solution to the supersymmetricCPproblem, and a supersymmetric explanation ofε′/ε Seesaw-constrained minimal supersymmetric standard model

We analyze CP violation in the minimal supersymmetric standard model (MSSM) embedded minimally at high scale into a left-right symmetric gauge structure with the seesaw mechanism for neutrino masses. Assuming universality of scalar masses we find that hadronic CP violation is described by a single phase in the supersymmetry breaking sector. In addition to providing a solution to the SUSY CP problem of the MSSM, it predicts ∈′/∈ arising purely from the supersymmetry sector in agreement with recent observations and the neutron electric dipole moment to be about 4×10-29 e cm. Additional predictions include a tightly constrained superparticle spectrum and vanishingly small CP asymmetries in the B meson system. ©2000 The American Physical Society.
