Natural Milli-Charged Inflation
arXiv:1405.6720 · doi:10.1103/PhysRevD.91.096012
Abstract
We construct a natural inflation model with the inflaton as a linear combination of the fifth components of Abelian gauge fields in a five-dimensional theory. A seesaw mechanism is introduced to provide a natural milli-charge for matter fields under one combination of the gauge symmetries. As a result, the effective decay constant of the inflaton field can be above the Planck scale with all scales in the model below the Planck scale. Our model predicts a tensor-to-scalar ratio r between 0.033 and 0.125 for sixty e-folds and a reheating temperature of a few 10^11 GeV.
