| Abstract | 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 $d_\mu / d_e = m_\mu / m_e$ and obtain a $d_\mu$ as large as $10^{-22\div -23}$ e cm. In most cases $d_\mu$ is around $10^{-24\div -25}$ e cm and ($d_\mu / d_e$)/($m_\mu / m_e$) 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 $\mu \to e \gamma$ and related processes. |
