A Little Higgs model of neutrino masses
Little Higgs models are formulated as effective theories with a cut-off of up to 100 times the electroweak scale. Neutrino masses are then a puzzle, since the usual see-saw mechanism involves a much higher scale that would introduce quadratic corrections to the Higgs mass parameter. We propose a model that can naturally accommodate the observed neutrino masses and mixings in Little Higgs scenar...
متن کاملNeutrino Masses in Composite Little Higgs Model
The composite little Higgs model, a UV completion for the SU(5)/SO(5) little Higgs model, incorporates supersymmetry into strong gauge dynamics. We extend the study of flavor physics in the model, and find that it is similar to the bosonic technicolor model. Lepton flavor violations and neutrino mass matrix arise once R-parity violating superpotential is introduced to the model, as in the MSSM....
متن کاملTesting neutrino masses in little Higgs models via discovery of doubly charged Higgs at LHC
We have investigated the possibility of direct tests of little Higgs models incorporating triplet Higgs neutrino mass mechanism at LHC experiments. We have performed Monte Carlo studies of Drell-Yan pair production of doubly charged Higgs boson Φ followed by its leptonic decays whose branching ratios are fixed from the neutrino oscillation data. We propose appropriate selection rules for the fo...
متن کاملNeutrino Masses, Lepton Flavor Violations, and Flavor Changing Neutral Currents in Composite Little Higgs Model
Little higgs theories attribute light higgs to being one of a set of pseudo Nambu Goldstone bosons. This implies that the UV cutoff of the little higgs models should be around 10 TeV, and a new physics resides above the UV cutoff. The composite little higgs model, a candidate for UV physics of the littlest higgs model, incorporates supersymmetry into strong gauge dynamics. We find that this con...
متن کاملSupersymmetric Triplet Higgs Model of Neutrino Masses and Leptogenesis
We construct a supersymmetric version of the triplet Higgs model for neutrino masses, which can generate a baryon asymmetry of the Universe through leptonnumber violation and is consistent with the gravitino constraints.
