Asymmetric Reheating of Dark QED
Simon Cléry, Jean Kimus, Michel H. G. Tytgat
We study in detail a scenario in which the inflaton scalar field couples to both a visible sector (VS) and a hidden sector (HS). The VS is assumed to contain the Standard Model (SM…
Generalizing the Bogoliubov vs Boltzmann approaches in gravitational production
Ayan Chakraborty, Simon Clery, Md Riajul Haque +2
We investigate the spectral behavior of scalar fluctuations generated by gravity during inflation and the subsequent reheating phase. We consider a non-perturbative Bogoliubov trea…
Bare mass effects on the reheating process after inflation
Simon Clery, Marcos A. G. Garcia, Yann Mambrini +1
We consider the effects of a bare mass term for the inflaton, when the inflationary potential takes the form about its minimum with . We concentrate on ,…
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…
