A Complete Analysis of “Flavored” Electric Dipole Moments in Supersymmetric Theories
The Standard Model predictions for the hadronic and leptonic electric dipole moments (EDMs) are well far from the present experimental resolutions, thus, the EDMs represent very clean probes of New Physics effects. Especially, within supersymmetric frameworks with flavor-violating soft terms large and potentially visible effects to the EDMs are typically expected. In this work, we systematicall...
متن کاملNeutrino CP phases and lepton electric dipole moments in supersymmetric theories
We analyse the dependence of the electron electric dipole moment (EDM) on neutrino CP violating phases in the context of supersymmetric models. We start by studying the supersymmetric contributions to the lepton EDM and lepton flavour violation processes τ → μγ and μ → eγ, in the framework of the mass insertion approximation, showing that, due to the large neutrino mixing, μ → eγ leads to sever...
متن کاملLepton Electric Dipole Moments in Non-Degenerate Supersymmetric Seesaw Models
In the context of supersymmetric seesaw models of neutrino masses with non-degenerate heavy neutrinos, we show that Dirac Yukawa interactions N c i (Yν)ijLjH2 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 ele...
متن کاملProbing Supersymmetric Baryogenesis: from Electric Dipole Moments to Neutrino Telescopes
We study the implications for electroweak baryogenesis (EWB) within the minimal supersymmetric Standard Model (MSSM) of present and future searches for the permanent electric dipole moment (EDM) of the electron, for neutralino dark matter, and for supersymmetric particles at high energy colliders. We show that there exist regions of the MSSM parameter space that are consistent with both present...
متن کاملLepton Electric Dipole Moments, Supersymmetric Seesaw and Leptogenesis Phase
Abstract We calculate the lepton electric dipole moments in a class of supersymmetric seesaw models and explore the possibility that they may provide a way to probe some of the CP violating phases responsible for the origin of matter via leptogenesis. We show that in models where the right handed neutrino masses, MR arise from the breaking of local B-L by a Higgs field with B-L=2, some of the l...
