چکیده

Now the bounds on the lepton-flavor violating (LFV) decay modes of tau lepton are being improved by the Belle experiment in the KEK B factory. In this paper the LFV decay of tau lepton is discussed in the supersymmetric seesaw model, using the current neutrino oscillation data.

Neutrino Masses, Lepton Flavor Mixing and Leptogenesis in the Minimal Seesaw Model

We present a review of neutrino phenomenology in the minimal seesaw model (MSM), an economical and intriguing extension of the Standard Model with only two heavy right-handed Majorana neutrinos. Given current neutrino oscillation data, the MSM can predict the neutrino mass spectrum and constrain the effective masses of the tritium beta decay and the neutrinoless double-beta decay. We outline fi...

Charged 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 ...

Flavor and CP Violation Induced by Atmospheric Neutrino Mixing

After discovery of the atmospheric neutrino oscillation by the superKamiokande experiment in 98’ [1], it is found that the lepton sector has much different flavor structure from the quark sector [2][3]. The seesaw mechanism is the most promising model to explain the tiny neutrino masses and the neutrino oscillation [4]. However, the observed mixing angles between the first and second and betwee...

Lepton Flavor Violating Process in a Supersymmetric Grand Unified Theory with Right-handed Neutrino ⋆

Motivated from the recent results of neutrino oscillation experiment, we investigated lepton flavor violating (LFV) processes in a SU(5) supersymmetric grand unified theory with right-handed neutrino. The current experimental upper bound for μ → eγ process gives already some constraint on the model. Correlation between μ → eγ and the SUSY contribution to the muon anomalous magnetic moment is al...

In these proceedings we present the results for lepton flavour violating tau and muon decays within the SUSY seesaw scenario. Specifically, we consider the Constrained Minimal Supersymmetric Standard Model extended by three right handed neutrinos, νR i and their corresponding SUSY partners, ˜ νR i , (i = 1, 2, 3), and use the seesaw mechanism for neutrino mass generation. We include the predict...
