Charged Lepton Flavor Violation in Supersymmetry with Bilinear R–Parity Violation
The simplest unified extension of the Minimal Supersymmetric Standard Model with bi-linear R–parity violation naturally predicts a hierarchical neutrino mass spectrum, suitable to explain atmospheric and solar neutrino fluxes. We study whether the individual violation of the lepton numbers Le,μ,τ in the charged sector can lead to measurable rates for BR(μ → eγ) and BR(τ → μγ). We find that some...
متن کاملCharged lepton flavor violation beyond minimal supersymmetry
We discuss charged lepton flavor violation in supersymmetric models with extended leptonic sectors at low energies. Contrary to the usual high-scale realizations of the seesaw mechanism, these non-minimal supersymmetric models have new superfields and/or interactions at the supersymmetric scale. As a consequence of this, the resulting lepton flavor violating phenomenology may be very different ...
متن کاملLepton flavor violation without supersymmetry
1550-7998=20 We study the lepton flavor-violating (LFV) processes ! e , ! 3e, and ! e conversion in nuclei in the left-right symmetric model without supersymmetry and perform the first complete computation of the LFV branching ratios B ! f to leading nontrivial order in the ratio of leftand right-handed symmetry-breaking scales. To this order, B ! e and B ! e are governed by the same combinatio...
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 کاملNeutrino-induced lepton flavor violation in gauge-mediated supersymmetry breaking
Gauge-mediated supersymmetry breaking is known to greatly suppress flavor changing neutral current effects. However, we show that gauge mediation in the context of leptogenesis implies potentially large lepton flavor violating signals. If the heavy righthanded neutrinos that participate in leptogenesis are lighter than the messenger scale of gauge mediation, they will induce flavor off-diagonal...
