Relic Gravity Waves and 7 keV Dark Matter from a GeV scale inflaton
We study the mechanism of generation of 7 keV sterile neutrino Dark Matter (DM) in the model with light inflaton $\chi$, which serves as a messenger of scale invariance breaking. In this model the inflaton, in addition to providing reheating to the Standard Model (SM) particles, decays directly into...
