Gravity as a Portal to Reheating, Leptogenesis and Dark Matter
Basabendu Barman, Simon Cléry, Raymond T. Co +2
We show that a minimal scenario, utilizing only the graviton as an intermediate messenger between the inflaton, the dark sector and the Standard Model (SM), is able to generate $si…
Gravitational Portals with Non-Minimal Couplings
Simon Clery, Yann Mambrini, Keith A. Olive +2
We consider the effects of non-minimal couplings to curvature of the form , for three types of scalars: the Higgs boson, the inflaton, and a scalar dark matter candidate…
Gravitational portals in the early Universe
Simon Clery, Yann Mambrini, Keith A. Olive +1
We consider the production of matter and radiation during reheating after inflation, restricting our attention solely to gravitational interactions. Processes considered are the ex…
