Electron and muon electric dipoles in supersymmetric scenarios Original Research Article

We study if a sizeable muon electric dipole can arise in supersymmetric frameworks able to account for the tight experimental bounds on sfermion masses, like an appropriate flavor symmetry, or like a flavor-blind mechanism of SUSY breaking (in presence of radiative corrections charchteristic of GUT models, or due to Yukawa couplings of neutrinos in see-saw models). In some cases it is possible to evade the naive scaling dμ/de=mμ/me and obtain a dμ as large as 10−22÷23e cm. In most cases dμ is around 10−24÷25e cm and (dμ/de)/(mμ/me) is only slightly different from one: this ratio contains interesting informations on the source of the dipoles and on the texture of the lepton Yukawa matrix. We also update GUT predictions for μ→eγ and related processes.
