In the context of the supersymmetrized seesaw mechanism embedded
in the Minimal Supersymmetric Standard Model (MSSM), complex
neutrino Yukawa couplings can induce Electric Dipole Moments
(EDMs) for the charged leptons, providing an additional route to
seesaw parameters. However, the complex neutrino Yukawa matrix is
not the only possible source of CP violation. Even in the
framework of Constrained MSSM (CMSSM), there are additional
sources, usually attributed to the phases of the trilinear soft
supersymmetry breaking couplings and the mu-term, which contribute
not only to the electron EDM but also to the EDMs of neutron and
heavy nuclei. In this work, by combining bounds on various EDMs,
we analyze how the sources of CP violation can be discriminated by
the present and planned EDM experiments.
