Inflaton freeze-out
Oleg Lebedev, Thomas Nerdi, Timofey Solomko +1
We study the possibility that, after inflation, the inflaton reaches thermal equilibrium with the Standard Model thermal bath and eventually freezes-out in the non-relativistic reg…
Dark matter production and reheating via direct inflaton couplings: collective effects
Oleg Lebedev, Fedor Smirnov, Timofey Solomko +1
We study scalar dark matter production and reheating via renormalizable inflaton couplings, which include both quartic and trilinear interactions. These processes often depend cruc…
Challenges for Inflaton Dark Matter
Oleg Lebedev, Jong-Hyun Yoon
We examine an intriguing possibility that a single field is responsible for both inflation and dark matter, focussing on the minimal set-up where inflation is driven by a scalar co…
