Axion Inflation: Perturbative control in the strong backreaction regime
Valerie Domcke, Alexandros Papageorgiou, Marco Peloso +1
We study the strong backreaction regime in axion inflation, in which the friction from Abelian gauge fields generated via the pseudo-scalar interaction $\fracβ{4 M_p} ϕF {\tilde F}…
Perturbatively including inhomogeneities in axion inflation
Valerie Domcke, Yohei Ema, Stefan Sandner
Axion inflation, i.e. an axion-like inflaton coupled to an Abelian gauge field through a Chern-Simons interaction, comes with a rich and testable phenomenology. This is particularl…
The Different Regimes of Axion Gauge Field Inflation
Valerie Domcke, Stefan Sandner
In axion gauge field inflation an axion-like particle driving cosmic inflation is coupled to the Chern-Simons density of an Abelian or non-Abelian gauge group. In the case of a non…
Reannihilation of self-interacting dark matter
Tobias Binder, Michael Gustafsson, Ayuki Kamada +2
We explore the phenomenology of having a second epoch of dark matter annihilation into dark radiation long after the standard thermal freeze-out. Such a hidden reannihilation proce…
