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} ÏF {\tilde…

Scale-dependent chirality as a smoking gun for Abelian gauge fields during inflation
Ogan Ãzsoy, Alexandros Papageorgiou, Matteo Fasiello
Axion-inflation models are a compelling candidate as a mechanism behind the accelerated expansion in the early universe in light of the possibility to embed them in higher dimensio…
