    We study the anomalous magnetic and electric dipole moments of charged leptons in supersymmetric low-scale seesaw models with right-handed neutrino superfields. We consider a minimally extended framework of minimal supergravity, by assuming that CP violation originates from complex soft SUSY-breaking bilinear and trilinear couplings associated with the right-handed sneutrino sector. We present numerical estimates of the muon anomalous magnetic moment and the electron electric dipole moment, as functions of key model parameters, such as the Majorana mass scale mN and tan β. In particular, we find that the contributions of the singlet heavy neutrinos and sneutrinos to the electron electric dipole moment are naturally small in this model, of order 10−27− 10−28ecm, and can be probed in present and future experiments.
