Abstract: (arXiv)

The tiny neutrino masses are most naturally explained by the seesaw mechanism through singlet right-handed neutrinos, which can further explain the matter-antimatter asymmetry in the universe. In this work, we propose a new approach to study cosmological signatures of neutrino seesaw through the interaction between inflaton and right-handed neutrinos. After inflation the inflaton predominantly decays into right-handed neutrinos and its decay rate is modulated by the fluctuations of Higgs field which act as the source of curvature perturbations. We demonstrate that this modulation produces primordial non-Gaussian signatures, which can be measured by the forthcoming large-scale structure surveys. We find that these surveys have the potential to probe a large portion of the neutrino seesaw parameter space, opening up a new window for testing the high scale seesaw mechanism.

We note that our model differs from the literature [20], where a right-handed neutrino is also introduced and its mass is modulated solely due to the Dirac mass term and the curvature perturbation is from the kinematic blocking of inflaton decays. In our model, the modulation arises from neutrino seesaw mechanism. Besides, the model of
