On the Seesaw Scale in Supersymmetric SO(10) Models
The seesaw mechanism, which is responsible for the description of neutrino masses and mixing, requires a scale lower than the unification scale. We propose a new model with spinor superfields playing important roles to generate this seesaw scale, with special attention paid on the Goldstone mode of the U (1) B−L symmetry breaking.
متن کاملDecay of Charged Higgs boson in TeV scale supersymmetric seesaw model
We discuss phenomenological consequences of some class of supersymmetric seesaw models in which the right-handed (s)neutrino mass is given to be TeV scale. In this scenario, scalar trilinear interaction of Higgs-slepton-(right-handed) sneutrino is enhanced. We show that the 1-loop correction by sneutrino exchange to the lightest Higgs boson mass destructively interferes with topstop contributio...
متن کاملHiggs - Mediated τ → 3 μ in the Supersymmetric Seesaw Model
Recent observations of neutrino oscillations imply non-zero neutrino masses and flavor violation in the lepton sector, most economically explained by the seesaw mechanism. Within the context of supersymmetry, lepton flavor violation (LFV) among the neutrinos can be communicated by renormalization group flow to the sleptons and from there to the charged leptons. We show that LFV can appear in th...
متن کاملSupersymmetric Model of Radiative Seesaw Majorana Neutrino Masses
The radiative seesaw mechanism proposed recently is minimally extended to include supersymmetry in a specific model. Relevant related issues such as leptogenesis and dark matter are discussed. If the standard model (SM) of particle interactions is extended to include three heavy neutral singlet Majorana fermions Ni (i = 1, 2, 3) and a second scalar doublet η = (η , η) with zero vacuum expectati...
متن کاملHiggs-mediated muon-electron conversion process in supersymmetric seesaw model
We study the effect of the Higgs-exchange diagram for the lepton flavor violating muon-electron conversion process in nuclei in the supersymmetric seesaw model. The contribution is significant for a large value of tanβ and a small value of a neutral heavy Higgs boson mass, in which case the ratio of the branching ratios of B(μN → eN)/B(μ → eγ) is enhanced. We also show that the target atom depe...
