Lepton Flavor Violation in SUSY models with U(1)–textures
U(1) family symmetries have led to successful predictions of the fermion mass spectrum and the mixing angles of the hadronic sector. In the context of the supersymmetric unified theories, they further imply a non-trivial mass structure for the scalar partners, giving rise to new sources of flavour violation. While τ → μγ decays are mostly expected to arise at rates significantly smaller than th...
متن کاملModels of Flavor with Discrete Symmetries
In an attempt to understand the observed patterns of lepton and quark masses, models invoking a flavor symmetry Gf , under which the Standard Model generations are charged, have been proposed. One particularly successful symmetry, U(2), has been extensively discussed in the literature. The Yukawa matrices in models based on this symmetry reproduce the observed mass ratios in the lepton and quar...
متن کاملSupersymmetric Lepton Flavor Violation
We study a new supersymmetric mechanism for lepton flavor violation in a minimal extension of the MSSM with low-mass heavy singlet neutrinos, which is fully independent of the flavour structure of the soft SUSY breaking sector. We find that l→ l′γ processes are forbidden in the SUSY limit, whilst the processes l→ l′l1l2 and μ → e conversion in nuclei can be enhanced well above the observable le...
متن کاملLarge Lepton Flavor Mixing and E 6 -type Uniication Models
There are experimental indications of large avor mixing between and. In the uniication models, in which the massless sector includes extra particles beyond the standard model, there possibly appear the mixings between quarks (leptons) and the extra particles. When large mixings occur, lepton avor mixings can be quite diierent from quark avor mixings. By taking the string inspired SU (6) SU (2) ...
متن کاملLepton Flavor Violation in Supersymmetric SO(10) Grand Unified Models
The study for lepton flavor violation combined with the neutrino oscillation may provide more information about the lepton flavor structure of the grand unified theory. In this paper, we study two lepton flavor violation processes , τ → μγ and Z → τμ, in the context of supersymmetric SO(10) grand unified models. We find the two processes are both of phenomenological interest. In particular the ...
