چکیده

We study SU($N$) gauge fields that couple to the inflaton through Chern-Simons term. provide a general procedure construct homogeneous, isotropic, and attractor solutions of during inflation. The develop various VEVs corresponding different spontaneous symmetry breaking patterns where embedded SU($2$) subgroups are broken with spatial rotation SO($3$) symmetry. As specific examples, we stable for $N = 3$ $4$. also numerically solve field dynamics confirm our analytic complete attractor. It is straightforward apply other simple Lie groups.

Natural Supergravity Inflation

We identify a new mechanism in supergravity theories which leads to successful inflation without any need for fine tuning. The simplest model yields a spectrum of density fluctuations tilted away from scale-invariance and negligible gravitational waves. We demonstrate that this is consistent with the observed large-scale structure for a cold dark matter dominated, critical density universe. The...

Natural Magnetogenesis from Inflation

We consider the gravitational generation of the massive Z boson field of the standard model, due to the natural breaking of its conformal invariance during inflation. The electroweak symmetry restoration at the end of inflation turns the almost scale-invariant superhorizon Z spectrum into a hypermagnetic field, which transforms into a regular magnetic field at the electroweak phase transition. ...

Saving Natural Inflation

Slow-roll inflation requires the inflaton field to have an exceptionally flat potential, which combined with measurements of the scale of inflation demands some degree of finetuning. Alternatively, the flatness of the potential could be due to the inflaton’s origin as a pseudo-Goldstone boson, as in Natural Inflation. Alas, consistency with Planck data places the original proposal of Natural In...

On: Natural Inflation

We re-examine the original model of Natural inflation, in which the inflaton is a pseudo Nambu-Goldstone boson with potential of the form V (φ) = Λ[1 ± cos(φ/f)], in light of recent data. We find that the model is alive and well. Successful inflation as well as recent data from the Wilkinson Microwave Anisotropy probe require f > 0.6mPl (where mPl = 1.22 × 10 19 GeV) and Λ ∼ mGUT , scales which...
