Scale-dependent chirality as a smoking gun for Abelian gauge fields during inflation
Ogan Özsoy, 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…

A novel PBH production mechanism from non-Abelian gauge fields during inflation
Ema Dimastrogiovanni, Matteo Fasiello, Alexandros Papageorgiou
We consider the case of axion-like particles (ALPs) during inflation. When coupled to a non-Abelian gauge sector via a Chern-Simons term, ALPs support an intriguing, testable, phen…
