Stability in Axion Inflation with Strong Backreaction from a Massive Vector Boson
Michael J. Baker, Joaquim Iguaz Juan, Lorenzo Sorbo
We study a modification of the model of axion inflation coupled to a gauge field where the vector field is massive. In the conventional scenario with a massless gauge field,…

Axion inflation in the strong-backreaction regime: decay of the Anber-Sorbo solution
Richard von Eckardstein, Marco Peloso, Kai Schmitz +2
Axion inflation coupled to Abelian gauge fields via a Chern-Simons-like term of the form represents an attractive inflationary model with a rich phenomenology, includ…
