  Abstract:
In the context of general Minimal Supersymmetric Standard Model (MSSM), new sources for Lepton Flavor Violation (LFV) as well as CP-violation appear. We show that in the presence of LFV sources, the electric dipole moment of the electron (de) can receive new contributions. In particular, de can receive a significant contribution at one loop level from the phase of the trilinear A-term of the staus, ϕAτ. We discuss how we can derive information on ϕAτ by combining the information on de with that on the LFV decay modes of the τ lepton. We then discuss if this approach can be considered as an alternative to the direct measurement of ϕAτ at ILC.
