Inflation and type III seesaw mechanism in $\nu$-gauge mediated supersymmetry breaking

TL;DR

This paper explores a model where type III seesaw mechanism fields act as messengers in gauge-mediated supersymmetry breaking, successfully linking neutrino physics, dark matter, and cosmic inflation consistent with current observations.

Contribution

It introduces a novel scenario where type III seesaw messenger fields facilitate inflation within a supersymmetric framework, aligning neutrino data with cosmological and particle physics constraints.

Findings

Model satisfies neutrino oscillation data

Consistent with dark matter abundance and Higgs mass

Predicted CMB spectrum aligns with observations

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.
