Scientific paper

In supersymmetric theories the radiative corrections due to heavy states could leave their footprints in the flavour structure of the supersymmetry breaking masses. We investigate whether present and future searches for the muon and electron EDMs could be sensitive to the CP violation and flavour misalignment induced on slepton masses by the radiative corrections due to the right-handed neutrinos of the seesaw model and to the heavy Higgs triplets of SU(5) GUT. When this is the case, limits on the relevant combination of neutrino Yukawa couplings are obtained. Explicit analytical expressions are provided which accounts for the dependencies on the supersymmetric mass parameters.
