Abstract
We discuss realization of cosmic inflation in the $\nu$-gauge mediated supersymmetry breaking scenario, in which a set of 24-dimensional chiral superfields responsible for the type III seesaw mechanism play the role of the messenger fields in gauge mediation. Using the data from neutrino oscillations, we show that the model satisfies constraints from the lepton flavor violation, perturbativity of the unified gauge couplings, the observed abundance of dark matter as well as the Higgs mass of 125.1 GeV. The predicted spectrum of the cosmic microwave background radiation fits well with the observation. We also comment on the falsifiability of this scenario by future experiments.
Highlights
Neutrino oscillations suggest that there is new physics beyond the Standard Model
A natural extension of the Standard Model to account for neutrino oscillations is to include a set of new fields that generate the neutrino masses, via the so-called seesaw mechanism [1,2,3,4]
Since supersymmetry is observed to be broken at low energy, understanding of the breaking mechanism is essential for phenomenological studies
Summary
A natural extension of the Standard Model to account for neutrino oscillations is to include a set of new fields that generate the neutrino masses, via the so-called seesaw mechanism [1,2,3,4]. Supersymmetry improves the Standard Model in several respects It controls the radiative corrections of the scalar sector while realizing electroweak symmetry breaking. The type III seesaw mechanism is realized by triplet fields with zero hypercharge, that play the same role as the right-handed neutrinos in the type I seesaw mechanism. These triplet fields are contained in Σi. The formulas of the neutrino mass matrix are collected in the Appendix
