1207.7328 (Federico R. Urban et al.)

Perturbations and non-Gaussianities in three-form inflationary
magnetogenesis
   [PDF]

Federico R. Urban, Tomi K. Koivisto
We reconsider magnetogenesis in the context of three-form inflation, and its backreaction. In particular, we focus on first order perturbation theory during inflation and subsequent radiation era: we discuss the consistency of the perturbative approach, and elaborate on the possible non-Gaussian signatures of the model.
