In the context of the supersymmetrized seesaw mechanism embedded in theMinimal Supersymmetric Standard Model (MSSM), complex neutrino Yukawa couplingscan induce Electric Dipole Moments (EDMs) for the charged leptons, providing anadditional route to seesaw parameters. However, the complex neutrino Yukawamatrix is not the only possible source of CP violation. Even in the frameworkof Constrained MSSM (CMSSM), there are additional sources, usually attributedto the phases of the trilinear soft supersymmetry breaking couplings and themu-term, which contribute not only to the electron EDM but also to the EDMs ofneutron and heavy nuclei. In this work, by combining bounds on various EDMs, weanalyze how the sources of CP violation can be discriminated by the present andplanned EDM experiments.Comment: 26 pages, 9 figures; added reference
