Inflationary Gravitational Leptogenesis
Raymond T. Co, Yann Mambrini, Keith A. Olive
We consider the generation of the baryon asymmetry in models with right-handed neutrinos produced through gravitational scattering of the inflaton during reheating. The right-hande…
Implications of the Non-Observation of in Halo Stars for the Primordial Problem
Brian D. Fields, Keith A. Olive
The primordial Lithium Problem is intimately connected to the assumption that observed in metal-poor halo stars retains its primordial abundance, which lies signif…
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…
BICEP/Keck Constraints on Attractor Models of Inflation and Reheating
John Ellis, Marcos A. G. Garcia, Dimitri V. Nanopoulos +2
Recent BICEP/Keck data on the cosmic microwave background, in combination with previous WMAP and Planck data, impose strong new constraints on the tilt in the scalar perturbation s…
