Lepton electric dipole moments in non-degenerate supersymmetric Seesaw models / Ellis, John R. (CERN) ; Hisano, Junji (KEK, Tsukuba) ; Raidal, Martti (CERN ; NICPB, Tallinn) ; Shimizu, Yasuhiro (Nagoya U.)
In the context of supersymmetric seesaw models of neutrino masses with non-degenerate heavy neutrinos, we show that Dirac Yukawa interactions N^c_i (Y_nu)_{ij} L_j H_2 induce large threshold corrections to the slepton soft masses via renormalization. While still yielding rates for lepton-flavour-violating processes below the experimental bounds, these contributions may increase the muon and electron electric dipole moments d_mu and d_e by several orders of magnitude.

Electron and muon electric dipoles in supersymmetric scenarios / Romanino, Andrea (Fermilab) ; Strumia, Alessandro (CERN)
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. [...]

Leptogenesis and the violation of lepton number and CP at low energies / Ellis, Jonathan Richard (CERN) ; Raidal, Martti
In the context of the minimal supersymmetric seesaw model, we study the implications of the current neutrino data for thermal leptogenesis, $\beta\beta_{0\nu}$ decay, and leptonic flavour- and CP-violating low-energy observables. We express the heavy singlet-neutrino Dirac Yukawa couplings $(Y_\nu)_{ij}$ and Majorana masses $M_{N_i}$ in terms of the light-neutrino observables and an auxiliary hermitian matrix $H$, which enables us to scan systematically over the allowed parameter space.

Lepton-Flavour-Violation in SUSY Models with and without R-parity / Tobe, K (CERN)
We discuss Lepton-Flavour-Violating phenomena such as $\mu \to e \gamma$, $\mu \to eee$, and $\mu \to e$ conversion in nuclei in SUSY models with and without R-parity. We stress that experimental searches for all the LFV processes are important to distinguish between the different models..

CP Violation in the Minimal Supersymmetric Seesaw Model / Ellis, John R. (CERN) ; Hisano, Junji (CERN ; KEK, Tsukuba) ; Lola, Smaragda (CERN) ; Raidal, Martti (CERN ; NICPB, Tallinn)
We study CP violation in the lepton sector of the supersymmetric extension of the Standard Model with three generations of massive singlet neutrinos with Yukawa couplings $Y_\nu$ to lepton doublets, in a minimal seesaw model for light neutrino masses and mixing. This model contains six physical CP-violating parameters, namely the phase $\delta$ observable in oscillations between light neutrino species, two Majorana phases $\phi_{1,2}$ that affect $\beta \beta_{0 \nu}$ decays, and three independent phases appearing in ${Y_\nu}{Y_\nu}^\dagger$, that control the rate of leptogenesis.
