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…
Nonthermal production of gravitinos and inflatinos
H. P. Nilles, M. Peloso, L. Sorbo
We explicitly calculate nonthermal gravitino production during the preheating period in the inflationary Universe. Contrary to earlier investigations, we consider a two--field mode…
Baryogenesis vs. proton stability in theories with extra dimensions
A. Masiero, M. Peloso, L. Sorbo +1
We propose a new scenario of baryogenesis in the context of theories with large extra dimensions. The baryon number is almost conserved at zero temperature by means of a localizati…
Preheating of massive fermions after inflation: analytical results
M. Peloso, L. Sorbo
Non-perturbative production of fermions after chaotic inflation has been the object of several studies in the very recent past. However, the results in the most interesting case of…
Dynamical Lorentz simmetry breaking from 3+1 Axion-Wess-Zumino model
A. A. Andrianov, R. Soldati, L. Sorbo
We study the renormalizable abelian vector-field models in the presence of the Wess-Zumino interaction with the pseudoscalar matter. The renormalizability is achieved by supplement…
