Neutron Electric Dipole Moment in the Minimal Supersymmetric Standard Model
Neutron electric dipole moment (EDM) due to single quark EDM and to the transition EDM is calculated in the minimal supersymmetric standard model. Assuming that the Cabibbo-Kobayashi-Maskawa matrix at the grand unification scale is the only source of CP violation, complex phases are induced in parameters of soft supersymmetry breaking at low energies. Chargino one-loop diagram is found to give ...
متن کاملConstraints from electric dipole moments on chargino baryogenesis in the minimal supersymmetric standard model
A commonly accepted mechanism of generating baryon asymmetry in the minimal supersymmetric standard model ~MSSM! depends on the CP violating relative phase between the gaugino mass and the Higgsino m term. The direct constraint on this phase comes from the limit of electric dipole moments ~EDM’s! of various light fermions. To avoid such a constraint, a scheme which assumes that the first two ge...
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...
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...
